The England manager named 30 players in his provisional squad and he admits he is dreading the moment when he has to reduce it to the 23 names he will submit to FIFA on June 1.
Asked if selecting his goalkeeper was the hardest decision he faced, Capello replied: 'No. Absolutely not. The hardest decision will be when I have to decide the 23 players and the seven that have to go home.

'They know I have to choose. You have to understand that I have to choose. But to be in the top 30 players of the national team is really important.
'I will decide on June 1 but I will phone the seven who will not go. We have to wait until after the Japan game (on Sunday) before making a final decision, to see if there are any injuries.'
D-day: Gareth Barry will discover on Tuesday whether his ankle injury will rule him out of South Africa
Seven names could become six on Tuesday if the specialist who examines Gareth Barry's ankle is not happy with the progress that has been made.
Last week Barry said he thought his ankle ligaments, damaged during Manchester City's 1-0 defeat by Tottenham at Eastlands on May 5, were healing well, but only if his medical staff are confident that the midfielder will train in another fortnight will Capello risk taking him to Rustenburg.
For Barry Tuesday is D-day.
