On the money or a waste of space? Here's our verdict on your Premier League side's buys

Angel di Maria and Diego Costa among the best summer buys for Manchester United and Chelsea respectively. But Bojan Krkic has struggled after falling out of favour at Stoke .Winless Newcastle have also seen Emmanuel Riviere and Remy Cabella fail to make an impact since summer transfer to Barclays Premier LeagueLiverpool and Arsenal seeing mixed form from transfer window arrivals .

ARSENAL 

Arsenal splashed out in the summer in a bid to sustain a Premier League title challenge. Alexis Sanchez has shown glimpses of his brilliance - and has contributed some important goals - but doesn't look completely up to speed with English football yet.

 Aston Villa left it until the last few minutes of the transfer window to sign Tom Cleverley from Manchester Utd

Mathieu Debuchy looked well suited to Arsenal before suffering his injury, while Calum Chambers has taken the step-up in his stride with some mature performances. 

Danny Welbeck has shown signs of improvement but can still be frustrating - his fine hat-trick against Galatasaray was the highlight. Jury is still out on reserve keeper David Ospina.

ASTON VILLA

There were plenty of doom merchants before the season about Villa's chances but everyone has been pleasantly surprised.

Their summer signings weren't eye-catching but they do make for a solid team. Colombian Carlos Sanchez is slowly getting up to speed with the pace of the Premier League, while Aly Cissokho is looking better than he did at Liverpool.

Philippe Senderos has looked reliable at the heart of the defence while Tom Cleverley has shown the odd sign he can put his Manchester United nightmare behind him.

Burnley 

Michael Kightly's move took time to go through but he looks like a good acquisition and broke the scoring drought at Leicester.

Matthew Gilks will be an understudy, while Matt Taylor has suffered an achilles injury and has not played since August. Marvin Sordell has not had a regular run of starts and has yet to open his account, while defender Steven Reid has barely featured.

CHELSEA

Diego Costa has come in and looked as though he's been playing in England for a decade, with an incredible run of nine goals in seven Premier League matches so far.

Cesc Fabregas is worth every penny of his £30m transfer fee. Filipe Luis has struggled to get into the side for league games, while the returning Didier Drogba is likely to spend most of the season on the bench as expected.

Loic Remy looks set to be in Costa's shadow too - but has opened his account. 

Despite costing £32million, Diego Costa has scored nine goals in as many games for Chelsea

CRYSTAL PALACE

Tony Pulis was so frustrated with Palace's lack of ambition in the transfer market that he left the club on the eve of the season. 

The Eagles, therefore, must be satisfied and relieved to be sitting 15th after seven games.

Eventually nine players moved to Selhurst Park in the summer, including club-record signing James McArthur.

He and Wilfried Zaha - who, like manager Neil Warnock - has returned for a second spell in south London - have both made decent starts to the campaign, as has two-goal striker Fraizer Campbell, a summer arrival from Cardiff. 

Most importantly of all, no key players left in the summer. 

EVERTON

It's been a disappointing start to the season for Everton and none of their summer signings have set the world on fire.

Romelu Lukau, so prolific last season, looks burdened by the responsibility of being the main man. Gareth Barry has done the important things with the minimum of fuss while Muhamed Besic looks like he could flourish.

HULL CITY

The Tigers spent unprecedented sums of money over the summer as they prepared for another Premier League season and a first run in Europe, which ended prematurely.

On the evidence of the season so far, Steve Bruce spent wisely, with Andrew Robertson looking a real gem and Mohamed Diame scoring three goals in four matches since arriving from West Ham.

Michael Dawson ended a nine-year stay at Tottenham Hotspur to bolster Hull's defence

Abel Hernandez has scored two goals so far, while Jake Livermore has continued to impress his manager.

Others, such as Hatem Ben Arfa, Michael Dawson and Gaston Ramirez could well impress when they settle into the team.

LEICESTER CITY

Newly-promoted Leicester didn't feel the need to spend big over the summer but they have acquired wisely.

Leonardo Ulloa, brought in from Brighton, has been excellent, scoring five goals so far and producing some eye-catching performances.

Esteban Cambiasso, 34, has rolled back the years with his passing and even hit the target in that incredible comeback against Manchester United. Full back Danny Simpson is waiting for a chance.

LIVERPOOL

After coming so close last season, Liverpool spent nearly £120m in strengthening over the close season, but the results have been mixed.

Adam Lallana, the most expensive buy at £25m, was very unfortunate with his injury but the signs have been encouraging since he returned last month. Alberto Moreno has also looked promising and scored in the 3-0 win at Tottenham.

 Since returning to the Premier League, Mario Balotelli has yet to score a top flight goal for Liverpool

MANCHESTER CITY

A quieter summer than usual at the Etihad, but still a substantial amount of money was splurged on new signings.

Eliaquim Mangala cost a cool £32million from Porto and – despite a nightmare at Hull – has all the tools required to be the powerful central defender alongside Vincent Kompany the Premier League champions have craved, as he showed on his debut against Chelsea.

Bacary Sagna is unlikely to dislodge Pablo Zabaleta at right back, although Fernando could become the main man in midfield given time. And Frank Lampard has shown he still has his eye for goal.

MANCHESTER UNITED

Wounded by a disastrous last campaign, United have broken the bank to try and restore them to the pinnacle of the Premier League.

Many have argued they have brought in too many attacking players and their defence certainly looks shaky.

Angel di Maria may have cost £59.7million but the Argentine is looking like one of the summer's best buys

Results are starting to pick up for Louis van Gaal's team, however. Angel di Maria has been absolutely exceptional, scoring and setting up goals, while Radamel Falcao got off the mark against Everton.

Ander Herrera looked classy in his passing before suffering a fractured rib, while Daley Blind has settled in straight away. The defenders Luke Shaw and Marcos Rojo have something to prove yet.

NEWCASTLE

Graham Carr was at it again. Newcastle splashed out around £35million over the summer and on European players who may or may not find their feet in England.

Remy Cabella, seen as the real blockbuster, has barely made any impact yet, while Emmanuel Riviere looks disinterested and incapable of mixing it up front.

Siem de Jong showed promise early on before suffering with injury, while Karl Darlow and Jamaal Lascelles both returned to Nottingham Forest on loan immediately after signing.

Jack Colback has probably been the standout thus far. He was free from Sunderland.

QPR

Harry Redknapp has been labelled a wheeler and dealer, but value for money appears to have gone out of the window at QPR.

A raft of new men have come in for big money but not improving the Championship play-off winners nearly enough.

Rio Ferdinand's experience has failed to prevent QPR from shipping 15 goals in just seven games this term

See £6m for Jordon Mutch. What about £8.5m for Steven Caulker? Not forgetting £8m on Leroy Fer. All three were relegated last season.

Goalkeeper Alex McCarthy is the club’s most progressive purchase but can’t get a look in thanks to Rob Green. Then there’s Rio Ferdinand.

SOUTHAMPTON 

The Ronald Koeman era has been brought in serenely at St Mary’s. Yes, they’ve had plenty of money to spend with Liverpool’s incessant need to buy the Saints spine, but they’ve parted with that cash very wisely indeed.

Graziano Pelle has all the attributes to become a real handful for Premier League defences, Dusan Tadic is a box of tricks and they’ve found themselves a solid goalkeeper in Fraser Forster.

Graziano Pelle has helped plug the gaps in the Southampton team which was left depleted in the summer

They’ve got away from signing big names – Gaston Ramirez and Dani Osvaldo spring to mind – and are steadily building a side that should comfortably finish in the top half.

Shane Long at £12m has been the only real disappointment. The less said about Saphir Taider – who left the club almost before he arrived - the better.

STOKE CITY

Bojan Krkic! At the Britannia! The new poster boy for a club (extremely unfairly) characterised as long-ball merchants.

Unfortunately, it’s not working out. The former wonderkid has more than a touch of Freddy Adu about him and hasn’t come anywhere near to living up to his teenage potential.
