New England captain Steven Gerrard admits he has mixed feelings about skippering the side at the World Cup.
The Liverpool ace has been handed the captain's armband by boss Fabio Capello after Rio Ferdinand was ruled out of the tournament on Friday when he suffered a knee ligament injury during training.
Gerrard admitted: "We're very disappointed about Rio but, by the time that first game comes around, I'm sure the team will be fit and ready to win.
"We're really excited. We've been given a super training camp at which to prepare. The guys are working hard to make sure they're fit and ready.
"It's fantastic for me to be able lead the country in the World Cup but obviously I'd rather that Rio was here fit and available so it's mixed emotions at the minute."
Meanwhile, Matthew Upson was the only member of the England squad who was unable to train on Sunday morning.
The West Ham United defender has been suffering from a high temperature that also led to him sitting out Saturday's session.
A Football Association spokesman said: "Matthew's feeling a lot better. He's working in the gym today and will train tomorrow (Monday)."
