BBC Sport reports. The Moroccan, who arrived on a free transfer from Bordeaux in 2010, has been on the fringes of the Arsenal squad this season, and large swathes of last season. This is a move which he will hope to be a spark for his career which has stalled somewhat. He will provide welcome cover for the Hammers though, with Andy Carroll out injured, he can expect to get some game time up front for the East London club. His experience in the Premier League will also no doubt be an asset. While he may not have made many appearances in the Premier League this season, Chamakh has gotten on the score sheet in the League Cup with two well taken goals in the thriller against Reading. The implications of this move for Arsenal are positive, Chamakh has long been a drain on wages and this could be seen as the first positive step made by the club to ease him out. West Ham make him their second signing in only 4 days after the capture of Joe Cole from Liverpool, with Big Sam surely targeting more players yet as the Hammers look to consolidate their place in the Barclays Premier League.
