Theo Walcott
Arsenal's Theo Walcott to miss the remainder of the season

Arsenal winger Theo Walcott, who refused to come off the field despite picking up a serious injury during the Gunners' goal-less derby tie with Chelsea, is likely to miss the remainder of the season adding more pressure on manager Arsene Wenger. The 23 year old's participation in the 2012 European Championships is also a doubt.

Wenger was upset when his Jamaica-born winger continued to play on for another three minutes before being replaced by Ivorian foward Gervinho in the 60th minute.

"He wanted to stay on the pitch and carry on but I felt he should have moved off straight away. The second time it was a real problem. It looks a serious hamstring. Now it will be tough to return before the end of the season," the Daily Mail quoted Wenger as saying.

Walcott, who has still not represented the Three Lions in a major competition, will probably miss on England's warm-up game against Norway on 26 May, ahead of the Euros being held in Poland and Ukraine. This could prove costly since England will be selecting their 23 member squad for the Euros following their second warm-up game against Belgium on 2 June. Walcott had earlier also been left out of the 2010 World Cup in South Africa by then England manager Fabio Capello, who later admitted he had made a mistake by not including him in the squad.

"He should be OK for England. I don't think he'll be ready to play for us," added Wenger.

Walcott, who started in only 15 games for Arsenal in the 2009/2010 season, has been facing a lot of problems with his shoulders, back, knee and hamstring throughout his career. However, he has been fairly fit this year, making 33 appearances for the Gunners.

Meanwhile, Tottenham Hotspur boss Harry Redknapp is expected to be officially crowned as the new manager of the Three Lions in the next couple of weeks.

The Spurs will be greatly affected, not only by the departure of Redknapp, but also by the departure of their other staff members including Kevin Bond (assistant manager) and Joe Jordan (first team coach), who will be joining the Three Lions with Redknapp.
