Every Premier League transfer window throws up its fair share of big name signings, but which stars have struggled since making a move in the summer? Tottenham Hotspur and Sunderland are teams with more than one name in the XI.
With Christmas just a matter of weeks away and the winter sales getting closer, Premier League clubs will be hoping for their versions of cheap bargains and quality players at a knockdown price once the January window opens.
Unfortunately for several sides, the purchases they've made in the summer can't be returned no matter how much they want to.
Whether they've been calculated signings or last-minute panic buys, not everyone that comes to the Premier League can be successful.
Tottenham's Moussa Sissoko in action with Sunderland's Papy Djilobodji
Despite £1billion's worth of talent changing hands and moving homes, a lot of players have failed to live up to expectations and although there's still half a season to go, opinions on these 11 summer signings couldn't be much lower.
Some players have been picked out because of their transfer fees, others for the fact they've been playing poorly, while others have just been strange signings who have failed to offer anything to their new club.
Only permanent signings have been considered for this list, but either way, here's a starting XI of the worst summer signings so far in the Premier League.
As always comment below and see what terrible team you'd pick instead!
Crystal Palace's Steve Mandanda
Steve Mandanda - Marseille to Crystal Palace
The experienced French international joined Crystal Palace on a free transfer as the supposed answer to Alan Pardew's goalkeeping woes.
Unfortunately he hasn't looked the safest pair of hands this season and his mistake against Burnley allowing Johann Berg Gudmundsson' shot to squirm through his body sums up his Palace experience so far.
The 31-year-old has kept just one clean sheet this season and that was a 2-0 win against Blackpool in the EFL Cup.
Sunderland's Paddy McNair in action with Southampton's Jack Stephens
Paddy McNair - Manchester United to Sunderland
Capable of playing as a defender or midfielder, but impressing in neither position, Paddy McNair is struggling to find his feet in the Premier League and looks out of his depth even at Sunderland.
According to Who Scored?, the Northern Ireland international has made just 0.3 interceptions and less than a tackle per game in eight appearances this season, ranking him as the worst defender in the league for interceptions and clearances.
Sunderland's Papy Djilobodji in action
Papy Djilobodji - Chelsea to Sunderland
McNair's teammate Papy Djilobodji has only looked marginally better and although he performed okay in the recent win against Bournemouth, the £8m signing needs to do much more to help Sunderland escape relegation.
Playing all of four minutes at Chelsea last season, with Jose Mourinho admitting he didn't sign him, Djilobodji's performances have been shaky for The Black Cats who have conceded 21 goals in the division this season and look destined for the drop unless they shore up defensively.
Mike van der Hoorn - Ajax to Swansea City
Ajax have a history of producing good centre backs in recent years with Thomas Vermaelen, Jan Vertonghen and Toby Alderweireld enjoying Premier League life at one time or another.
Yet Mike van der Hoorn looks lost in a Swans backline that's conceded the same as bottom club Sunderland. He didn't turn out much for Ajax making just 33 Eredivisie appearances in three years, but Bob Bradley will be hoping the 24-year-old eventually comes good.
Sofiane Feghouli - Valencia to West Ham United
His free transfer from Valencia to the London Stadium was heralded as a massive coup for West Ham, but for one reason or another it's not happened for Sofiane Feghouli.
In nine appearances, he's only registered one goal which came in a Europa League tie against Domzale back in August and two starts.
The Algerian has stayed firmly on the bench for most of this season making just five substitute appearances in the league and the 26-year-old needs to up his game to help West Ham climb up the table.
Southampton's Matt Targett in action with Manchester United's Henrikh Mkhitaryan
Henrikh Mkhitaryan - Borussia Dortmund to Manchester United
Consistently one of Europe's brightest attacking midfielders with 11 goals and 15 assists in the Bundesliga last season, Henrikh Mkhitaryan has lost out to the likes of Jesse Lingard and Marouane Fellaini for a place in Manchester United's team.
Jose Mourinho does not like the look of the £27m signing at all, with just one Premier League start coming in the Manchester derby of which he was hooked at half time.
He recently surfaced against Fenerbahce for his first appearance in two months, unsurprisingly coming off the bench.
Tottenham's Moussa Sissoko
Moussa Sissoko - Newcastle United to Tottenham Hotspur
One of the strangest moves in the transfer window came on deadline day where Tottenham willingly paid £30m to Newcastle for Moussa Sissoko on the back of a solid Euro 2016 for beaten finalists France.
It's safe to say Spurs are yet to be repaid for the midfielder's performances. A woeful performance against Bayer Leverkusen at Wembley and a three-match ban for elbowing Bournemouth's Harry Arter are the only highlights of Sissoko's time at Spurs.
He doesn't look like a Mauricio Pochettino at all and has a lot of convincing to do at White Hart Lane.
Bournemouth's Jordon Ibe in action with Everton's Idrissa Gueye
Jordon Ibe - Liverpool to Bournemouth
Eyebrows were raised when Jurgen Klopp sanctioned the sale of Jordon Ibe to Bournemouth for £15m but you can understand why that's the case.
Inconsistency has been a major blot on the 20-year-old's short career and at the Vitality Stadium, he's failed to register a single goal or assist or finish 90 minutes.
Time is on the former Liverpool winger's side but he's being upstaged by the likes of Junior Stanislas and Joshua King.
Hull City's Will Keane
Will Keane - Manchester United to Hull City
A thread-bare Hull City squad was suddenly bolstered with four names in the last two days of the summer window, with Manchester United striker Will Keane linking up with former United assistant manager Mike Phelan on Humberside.
But a career yielding just five goals in 58 appearances is an awful return for the 23-year-old who does not look like the striker capable of firing Hull to safety.
You sense his arrival, along with midfielder James Weir from Old Trafford was an act of desperation to get bodies in at the KCOM Stadium to help keep Phelan's first teamers fit to try and avoid the drop.
Tottenham's Vincent Janssen
Vincent Janssen - AZ Alkmaar to Tottenham Hotspur
The struggles of Vincent Janssen are well-documented, but the Dutchman just doesn't look up to scratch at Tottenham with his hold-up play at odds with the club's quick press and push-and-run tactics.
For £17m, three penalties is not good value for money and with Harry Kane back to fitness, Janssen is set to serve as back-up to the England man.
Chelsea's Michy Batshuayi celebrates scoring their first goal
Michy Batshuayi - Marseille to Chelsea
For £33m, you'd expect more than 76 minutes of Premier League action and if you were Michy Batshuayi, you'd be understandably annoyed.
What's even worse is those 76 minutes have come across eight Premier League games. Always going to be difficult to displace Diego Costa when he's in formidable form, but the Belgian will feel like he's not being given a chance to shine at Stamford Bridge which hasn't always been a happy hunting ground for strikers.
Three goals in 11 appearances was not what the 23-year-old was expecting who has continued to suffer as Antonio Conte's 3-4-3 system means there's no hope of him staking a claim for a starting spot.
