Wayne Rooney believes there is a new relaxed atmosphere surrounding the England camp following the recent upturn in results.
The Manchester United striker missed the last two Euro 2008 qualifying victories over Israel and Russia after suffering a fractured metatarsal injury.
But after returning to the international fold for the first time this season, the 21-year-old forward has sensed an ease in the tension that was present before the recent back-to-back 3-0 victories.
"I'm delighted to be back after being out of the squad," he said.
"The atmosphere from when I was last in the squad is a lot different.
"I've noticed a change. It's more relaxed around the hotel. We've had some good results over the last few games and I'm sure that has helped the atmosphere in the team and hopefully it will help us in the next matches."
Rooney is relishing the prospect of facing Estonia and Russia in five days and believes England can continue their resurgence in two must-win games.
"We're confident and we've trained well and we're looking forward to the games," he continued.
"I think if we can get three points on Saturday and then go to Russia and get a good result we'll be happy.
"Although I haven't been involved for a while I've watched the games and I think they have done really well.
"I'm an England fan as well and if I'm not playing I want them to play as well as they can and get the best result. In the last two games I watched and they did that.
"We know they are two big games for us and hopefully we can get the right results and be almost in the tournament."
