Mikel Arteta demands that Arsenal step up a level in pursuit of Champions League place We should have won at Bolton. We had a lot of chances to win the game comfortably in the first half, but, once again, we've not been good enough to take them. And if you don't take your chances it's always going to be difficult. Arsenal face another relegation-threatened side, Blackburn, this weekend and they know time is running out if they are to overhaul Chelsea, Liverpool and Newcastle in the race to finish fourth. "We should win against Blackburn," Arteta said. We lost against them away from home and we should have won that one. We know they are going to make it tough as they are in a relegation battle and we know how hard teams in that situation battle. It's going to be tough to finish in the top four, but I think we have the quality and the desire to do it. The Arsenal Supporters" Trust, meanwhile, has said that members will be surveyed during the summer about Wenger's performance. Supporters have been showing unprecedented dissatisfaction towards Wenger but the AST believes that the club's most successful-ever manager can only be judged at the end of the season. There is considerable frustration among fans at the lack of spending during the January transfer window, particularly as the club have available funds of around £50 million. Arsenal's only additions in January were the short-term loan signing of Thierry Henry and the £600,000 addition of German teenage midfielder Thomas Eisfeld. The AST also intends to write to the Arsenal owner, Stan Kroenke, to request a meeting and further engagement with fans.
