Top flops: Who are Premier League's under-performers?

Luis Suarez and Eden Hazard are leading the way in the race for the Premier League's star of the season award, but at the other end of the spectrum, the gong for the worst-performing player of the current campaign is up for grabs.

Quite what Kagisho Dikgacoi provides for Crystal Palace, on top of a lot of running, is hard to fathom. No goals or assists from 21 shots and key passes hints that he should be a combative, ball-winning central midfielder, but with 1.6 tackles and 1.2 interceptions per game, he doesn't even rank in the top 10 for either statistic at Crystal Palace. In fact, there are 22 Premier League central midfielders who fare better than him, and this is meant to be the area in which he contributes most. Kim Bo-Kyung played a huge part in getting Cardiff into the Premier League, but the step up seems it might have been too great. Creation isn't his forte, yet to register a single assist so far this season, and he isn't good in the air, with three aerial duels won from 35 contests. His 18 accurate passes per game is down there with the lowest amongst central midfielders in the league and he does not win possession enough. Kim would be a prime candidate for the 2013/14 Premier League's 'jack of all trades, master of none' award. Cardiff teammate Declan John came into the starting team midway through the season but hasn't done much to convince fans that he is deserving of the spot, having obtained status as the Premier League's worst full-back (average rating 6.32). Naturally cautious given his tender years, John provides extremely little attacking threat (four accurate crosses in 14 appearances), and has only made 13 tackles and seven interceptions. Worryingly for Cardiff, their only other natural left-back, Andrew Taylor, has been the second worst in the whole Premier League. Ondrej Celustka has been almost as disappointing since signing for Sunderland last summer; he has started 14 Premier League games but only been on the winning side twice, and it is no coincidence that the Black Cats have scored only seven times with him on the pitch, with the Czech making only 2 key passes in 19 appearances. Centre-backs Marc Wilson and Alex Bruce make up the defence, with the latter's 1.9 aerial duels won per game no fewer than the 65th-highest of Premier League central defenders. Wilson ranks only four places above him in this regard, while both also come up at the wrong end of the rankings when looking at the number of times they are dribbled past. In goal, Keiren Westwood completes the XI, and his stats only serve to reinforce the view that Vito Mannone has been Sunderland's best signing in recent times. Westwood's pass success rate (37%) is the worst of all players with at least one start in the Premier League this season, while his save success rate (60.4%) is down there at the wrong end of the top flight's stoppers. Mannone's (79.4%), in comparison, is the best in the league.
