With the January transfer window now open, managers all around the world are now free to pursue their transfer targets as the second half of the 2016/17 season gets underway. Here's a list of 11 players who shouldn't be anywhere near the starting lineup of their current clubs at the moment - some of whom may well be replaced before the transfer window slams shut... With just one clean sheet so far this season, Josip Posavec is the worst-performing goalkeeper in Europe's top five leagues,...
Since signing for over £20m from Zenit St Petersburg, Ezequiel Garay has been something of a curse for Valencia, who have only won one of the eight games that he has started so far this season - conceding 15 goals in the process.
Since signing from Barcelona, Claudio Bravo has struggled for clean sheets and has succeeded in spreading panic throughout his defence in far too many games this season.
With Joe Hart still on their books, it seems a little odd that Bravo is still Pep's first-choice goalkeeper.
No player in Europe's top five leagues has received more cards than Sporting Gijon's ill-disciplined Fernando Amorebieta, who has received 10 yellow cards in 14 games.
The defender, who is somehow yet to receive a red card, has been suspended more than once already this season for the 18th placed La Liga side.
In 16 Premier League appearances since his summer move to Manchester City, John Stones has more defensive errors to his name than he does clean sheets (two errors, one clean sheet).
Vincent Kompany seems to be injured all the time and Aleksandar Kolarov hasn't exactly set the world on fire with his performances alongside Nicolas Otamendi in place of Stones, but for £50m, Pep must've expected a lot more.
Since ending 2015 as the top goalscorer in all of English football, Odion Ighalo's career has been on the decline.
This season, the Nigerian international has just one league goal to his name and despite hardly threatening to score more often than not, he has started the majority of Watford's fixtures. A striker who can't score surely shouldn't be guaranteed a starting spot?
With a shot accuracy of just 33%, Borja Baston is still yet to have five shots on target in the league for Swansea after his club record £15.5m move - awful in comparison to Swansea's other striker, Fernando Llorente, who has six goals, 66% shot accuracy and only cost £5m.
Last season, Hatem Ben Arfa was one of the best-performing players in France with 17 goals and six assists to his name. This year he has one assist and zero goals.
His poor form is matched by an equally poor attitude, and with the Frenchman recently reduced to sporadic substitute appearances, it would appear as if Unai Emery also believes that Ben Arfa does not deserve to command a starting place at his club.
Loris Karius joined Liverpool for a relatively small fee considering how impressive he was for Mainz, Jurgen Klopp's former club, in the 2015/16 season where he was named in the Bundesliga Team of the Year.
At Liverpool, however, he has been far from impressive and deservedly lost his place to Simon Mignolet after conceding 12 goals in 10 games - making just 14 saves in the process.
Another forward who can't seem to buy a goal at the moment is Dieumerci Mbokani, who has never scored for Hull City since joining on-loan from Dynamo Kyiv.
Mbokani, Abel Hernandez, Adama Diomande and Will Keane have just three goals between them this season - the same amount as centre-back, Michael Dawson.
No defender in Europe's top five leagues has made more mistakes than Watford's Sebastian Prodl, who has made five already this season - two of which led directly to goals.
The Austrian has only kept three clean sheets so far, conceding 36 in the 19 other league games.
With just one clean sheet so far this season, Josip Posavec is the worst-performing goalkeeper in Europe's top five leagues, having conceded 35 goals in just 18 games.
On top of this, Posavec also leads the way for number for the amount of defensive errors committed, with five - four of which led directly to goals.
