David Beckham suffered 'psychological difficulties' after being dropped by Steve McClaren, claims Real Madrid manager Fabio Capello.
The 31-year-old resigned as England captain after the World Cup in Germany before being axed from the squad after McClaren succeeded Sven-Goran Eriksson as England manager.
Now Beckham's future at the Bernabeu is under question after he stalled on signing a new contract following his lack of involvement in the Real team since Capello was appointed manager.
However, the Italian believes Beckham's omission from the England set-up has had serious repercussions for the former Manchester United star.
He told Sky Sports: 'I think Beckham is an outstanding professional. He always gives his best both in training and when he is playing.
'But a coach needs the overall picture. In Beckham's case, he has had bad times after being left out of England's national team.
'Those are moments which produce psychological difficulties. Now he's regaining all his composure.
'The other day in the Champions League he played very well and now he seems to have become the Beckham we once knew. But I think the hardest test for him was to stop being captain of the England team.'
