Fergie and Wenger back Fabio's decision to axe Beckham

The Los Angeles Galaxy midfielder was the headline omission from the England squad with Capello citing the former national team skipper's lack of match fitness as he sought to win his 100th cap.

Ferguson said it was a "straightforward" decision based on Beckham's fitness as the 32-year-old has not played a competitive game since England's defeat against Croatia in November.

Joining in: Beckham training at Arsenal

The Manchester United boss said: "I am not surprised he has been left out. What Fabio has said is that David is not match fit.

"He wants players who are match fit and David has not played any football.

"That is the reason he has not been picked. It is straightforward."

Ferguson added: "You have to think of Fabio's position. He has to win that game.

"It is an important match as it is his first as manager of England and he is a foreign coach with a great reputation."

Wenger also claimed Capello had made the right decision but backed Beckham to reclaim his spot and admitted he was 'amazed by how good' he was during his recent month-long training stint with Arsenal

The Los Angeles Galaxy midfielder spent four weeks with the Gunners in a bid to retain his fitness following the conclusion of the Major League Soccer season.

He told Arsenal TV Online: "He worked with us for four weeks.

"We gave him the first two weeks exclusively on fitness work with (fitness coach) Tony Colbert.

"After (that) he was with us in and out but in the third week he was a lot with us

"And we were all amazed how good he was."

The Arsenal manager also believes that because Beckham is so important for England that he will return to win his century of caps.

"I believe the English national team still needs Beckham because he can still make decisions and his experience will be needed in the big games and that is why I am sure he will get his 100th cap."

Wenger also paid tribute to the fight and resilience Beckham has shown throughout his career and which convinces the Gunners chief he will return to the England team.

He continued: "First of all Capello picks on the performances - that is what I rate and what I pick is right.

"I believe that what is in Beckham's mind is that I would like to get the 100th cap on performance and on merit not on sentiment.

"Having worked with Beckham here I must say one thing. He has worked extremely hard, that this guy will not give up and will continue to fight.

"The second thing I believe as well is that it would be unfair to Beckham to give Beckham the 100th cap just because you have done well, let's give you one.

"This guy deserves a lot of credit, every day he was first out, last in and give him competitive games with LA Galaxy and he will fight for his 100th cap."
