2. Calum Chambers – Chambers isn’t good enough for Arsenal. The former Southampton man is a squad player, and little more. It is a shame that he hasn’t adapted to life at the Emirates, but an exit could be suited to both parties. 5. Per Mertesacker – Mertesacker has to go. Wenger’s confidence in the Germany international is bizarre; so often does he look out of his depth battling in England’s top flight, but for as long as he stays, he will remain a regular on the team-sheet. The 31-year-old is not the answer to a John Terry or a Vincent Kompany at Arsenal, and Wenger has to step into the transfer market and acquire an experienced centre back that can partner Laurent Koscielny. Mertesacker isn’t the man for the job. Arsenal have left even rival supporters in disbelief at their performances this season. With Chelsea, Manchester City and Manchester United struggling in the Premier League, this season should have seen the Gunners run away with the title. Instead, manager Arsene Wenger’s side have remained as inconsistent as ever, with injuries, a lack of leadership and a lack of activity in the transfer market – to name but a few– continuing to hinder their ability to challenge for top spot.With all this in mind, it could now be time for Arsenal to engage in a major overhaul of their senior squad in the summer.But which players’ futures in north London may be under threat?Take a look at six players the Gunners could offload at the end of the season by viewing the slideshow above. 4. Olivier Giroud – After this season, Wenger has to address his striker options. At the beginning of the campaign, Theo Walcott was the preferred option to lead the line before – predictably – injury forced the return of Giroud. While both regularly found the net early on, the second half of the season has seen their goals to game ratio alarmingly drop. Arsenal simply don’t have a centre forward that can perform consistently, nor do they have one that intimidates their opponents. Giroud is not the answer. 6 6 3. Jack Wilshere – He may well be set to return from injury soon, but just how long will it be until he suffers another setback and returns to the recovery room? Looking at his track record suggests it won’t be long. Arsenal may well be at fault for his fitness problems, but who’s at fault – if anyone – is irrelevant. The Gunners have to address his role. As a homegrown player, his market value likely remains high and cashing in could be a wise decision, particularly as they desperately require an established defensive midfielder. 6. Theo Walcott – Walcott is among the most frustrating players in England’s top flight. For all his pace, he often has little to show for it and patience may now be wearing thin. His future was uncertain last season, with his contract expiring, but having penned a new four-year deal in the summer, he was expected to finally kick on as a regular in the first team. Despite a promising start to the current season, though, his contribution hasn’t been enough. The fact is he isn’t good enough to fire Arsenal to a Premier League title. Whether Wenger agrees, however, is debatable. 6 1. Alex Oxlade-Chamberlain – take a look at five other players whose futures in north London are in danger by clicking the arrow above – This season has seen supporters finally question the Ox’s development. The winger has spent over four and a half seasons at Arsenal, but what he has contributed to the club during this time has been minimal. His performances have showed few signs of improvement, making it difficult to envisage him becoming a regular in the senior squad. He may only be 22, but having spent such a significant chunk of his career in the Premier League, there is little argument that he shouldn’t now be performing consistently. Liverpool and West Ham have both been linked with his signature – cashing in might not be such a bad idea. 6 6 6 read more
