Capello's side next play Kazakhstan away on 6 June
England coach Fabio Capello paid tribute to his players after they overcame Ukraine to maintain their 100% record in World Cup 2010 qualifying.
"I'm happy because we won the game - it was very important because we knew Ukraine would be a very strong team," Capello told BBC Radio 5 Live.
"They've just started their league and are fresh, while we are at the end of our season. This is a big difference.
"The players played very well and without fear."
England have won all five of their group six matches and are five points clear of second-place Croatia.
They took the lead against Ukraine when Peter Crouch volleyed home but, after Andriy Shevchenko looked to have earned his side a draw with a 74th-minute equaliser, it required a late effort from John Terry to wrap up the victory.
"We played the first half very well, the second a little less," said Capello, whose only defeats as England manager came in friendlies against France and Spain.
"In midfield we lost a lot of balls and the movement was not as we had prepared.
"We played slowly and missed a lot of easy and important passes. Ukraine were fresh so we needed to play more quickly and this is impossible with us at the end of our season. The fans were very good, noisy when they needed to be, and they helped us."
