Arsene Wenger believes Sol Campbell's experience could prove a crucial asset if the veteran defender stays on at Arsenal next season - and sees no reason why the 35-year-old should not go to the 2010 FIFA World Cup™ with England.

Campbell, who rejoined his old club during January on a short-term contract after leaving Notts County, produced a composed display at the heart of a makeshift backline alongside fellow senior campaigner Mikael Silvestre as Arsenal all but secured third place in the Premier League following a goalless draw against Manchester City at Emirates Stadium.

England manager Fabio Capello was in the stands - although perhaps more to assess the efforts of Arsenal winger Theo Walcott, along with City's World Cup hopefuls Adam Johnson, Gareth Barry and Micah Richards than take a considered look at Campbell.

Wenger, though, feels Campbell's presence within his own squad, both on and off the pitch, has proved some much-needed nous, even if it could not ultimately help his youthful side deliver a trophy.

"I believe it is fantastic to see how well Sol has come back. When he has his mind on the game he is unbelievable," said the Arsenal boss, who is in the process of discussing with Campbell options for a possible new contract. "Sol is a strange guy because when he is focused sometimes he can be very detached - but when he is in with you, he is 100%, not 99, that is what I like.

"In the dressing room as well he has been very good. If Sol sets himself a target he is an unbelievable soldier," he also said.

Wenger believes Campbell, a former England skipper, still has something to offer the national team, his last of 73 caps - including three World Cups - having come in the defeat to Croatia at Wembley which ended hopes of reaching the 2008 European Championships.

"I just see that many centre-backs are injured, so why not?" said the Arsenal boss. "Sol has got the experience and it is up to Capello to decide. Of course others have an advantage because they are younger, but if England have a problem in numbers Sol is always there. I do not select the team and I do not say Capello has to take him - I just say you compare him today in the Premier League with the other centre-backs and he does not suffer in the comparison."
