Fergie will probably take the same attitude he has for the last few seasons, clap him on the back for stockpiling goals against the bottom 12 teams, before expressing bemusement when he's marked out of the knockout European games yet again.
Ah now that's a bit harsh. Last year rooney scored two goals against man city in the cup, and in the league, three goals against arsenal, Two goals against spurs, three goals against chelsea, two goals against everton, two goals against liverpool and two goals against fulham. The only team in the top nine that he didn't score at least two goals against was Newcastle.
Even then in the knockout stages in europe over the last three seasons Rooney scored four goals against AC Milan, and one against bayern munich, before getting injured. Then the season after that he scored the winner at chelsea, the second goal at schalke, and scored in the final. Then last season he scored 3 goals against bilbao.
There's plenty of reasons to criticize rooney, but the coverage of him generally has the attention span of a gnat. By any historical standards, He scores an absolutely extraordinary number of goals for manchester United, and he scores them in big games. He doesn't score in every big game, but it's still an awful lot of goals.
