Chelsea lionheart Terry is back to 100 per cent fitness after missing England's first game against France with a hamstring problem. And he is concentrating entirely on keeping Croatia at bay.

The big centre-back enjoys keeping clean sheets every bit as much as Wayne Rooney loves scoring goals. So there is no chance of him lacking focus when England run out in Lisbon on Monday night.

Terry said: "Getting a clean sheet against Switzerland was very important and very encouraging for us. And it will be the same against Croatia.

"We know that if we keep a clean sheet we have plenty of ability to score goals at the other end.

"We do a lot of work with Steve McClaren in training on defence. We work defending as a group and we are beginning to gel as a group of players. Croatia are very good from set pieces and we're aware of that and we'll go through more about them at training tonight. But we'll be ready."

Terry is proving himself a key member of the England squad after forcing his way into the side following the suspension of Rio Ferdinand. And his partnership with Sol Campbell is growing in stature game by game.

"I enjoy playing alongside Sol," said Terry. "We work well together and it's encouraging when we keep a clean sheet. I get the same feeling from that as I do when we're scoring goals.

"I'm certainly enjoying it here. I was disappointed to miss the France game but it was a great achievement to be part of such a great tournament and make my debut against Swtizerland. The hype surrounding the tournament is big and I was a little nervous, but I enjoyed it.

"Thankfully, I'm fully over the injury now. I was a little disappointed with the way I started against Switzerland, but I'm feeling fine."

Terry will come up against an old foe when he faces Croatia - because star striker Dado Prso is a certainty to start for England's opponents.

Prso played against Terry for Monaco in the semi-finals of the Champions League, scoring one of the goals in a 3-1 first-leg win for the French side and then coming on as a substitute in the second leg at Stamford Bridge to help them draw 2-2.

It is a painful memory for the Chelsea defender, and he has taken time to study Prso's game to make sure the same thing doesn't happen again.

He said: "After the Monaco game I watched back a video of it. And Prso is a fantastic player, always a threat. But I have played against him a couple of times and hopefully learned a little about him so I can stop him."

If Terry can do that on Monday night it could go a long way to ensuring England qualify for the quarter-finals of Euro 2004.
