8. Marouane Chamakh (West Ham)
Although only brought in on loan from Arsenal, the Moroccan striker has been a complete waste of time for West Ham, barely featuring since agreeing to join the Hammers, and looking every bit as ineffectual as he did in his two years at the Emirates Stadium. Even though he was a free transfer for Arsenal as well, his lack of killer instinct in front of goal makes him one of the worst ever Premier League signings, not just one of the worst this season. It’s hard to imagine anyone taking a punt on him next season, when presumably neither Arsenal nor West Ham will make any effort to keep hold of him. One to forget for Sam Allardyce, who has shown he can use the loan market well, with Andy Carroll coming in from Liverpool and doing a much better job. As for Chamakh, he looks set to finish this season with an amazing record of one Premier League goal in two years. To put that into some context, that’s a record as good Everton goalkeeper Tim Howard.
