No big shock when you consider this comment from Williams in the Guardian

Since then Rooney's all-round technical skill, his physical strength and his appetite for the game have persuaded his coaches, at both club and international level, to invite him to solve their tactical problems by accepting a variety of roles.

At the end of a long season, however, Rooney looked jaded and even earned a booking last night. The effort was certainly there, but the vision was awry and the touch haphazard. Seven of England's starting line-up had played in that exhausting encounter in Moscow a week earlier, five of them from the start to the finish of the 120 minutes, and although Rooney was withdrawn, much to his evident chagrin, in the 101st minute against Chelsea, he seemed to be suffering the most from the blunting of his edge.

Rooney is still a young man and a summer break should do him the world of good. Cap will need him ready in the fall for the World Cup qualification games.
