Do you think England, as a team, will play better with Rooney on the field?
The secret to win is rather simple... have world class players. Anytime & anywhere. Then there is luck, of course.
Given that Rooney is a world class striker, YES, he should make the difference. But of course let's not forget what happened to Messi during the WC... the best player out there but if your midfield can't give him good, decent balls he has nothing to do.
Whatever, great players make the difference, so yes, Rooney necessarily improves the English team.
It should be as you say. But several times I have noticed that the other players relax when they have a star on the pitch. It seems like they think "lets give the boll to the star and we will win" and thereby do less themselves.
I've seen the English team with Rooney make worse games than they have so far in the tournament. With that said I look forward seeing England improve their game tommorow.
