England captain Wayne Rooney believes his game has improved for the better, amid questions over his involvement in the squad for the Euro 2016.
England will face Russia in their opening game, after winning all three of their pre-tournament warmups.
With Rooney scoring just eight Premier League goals this season, his place in the side has come under scrutiny but the 30-year-old – who has adapted to a role in midfield for Manchester United in recent times – still has great confidence in his abilities.
“I think everyone who watches the game is entitled to their opinions, I know the qualities I have and I don’t think I have to sit here and defend myself,” Rooney told reporters.
“I have played this game for a lot of years and I am aware my game has changed over years, in my opinion for the better.
“I changed my game slightly. I’ve seen players do that over years, who have played in a different way to what they did and became better players, it’s natural for a footballer.
“Over last few months at Man U I’ve played midfield, it’s a natural way of football, it happens. I always feel with my football intelligence I can play there and further my career there as well.”
On England’s prospects at the tournament, he added: “There is a real buzz around the place and everyone is excited, it is important performance levels match.
“We’ve got a talented squad capable of big things, but tournament football is different. It will be a challenge for us as a squad but we’re confident we can do well.”
