ManU What Happened?

With Ronaldo and Rooney gone, its like ManU has lost its backbone. The game played with Rooney and Roanldo in the team differs a lot then the game played without them. When I watched the first league game of ManU, I had thought that ManU will surely win the league title in a row. Their game was just superb. And Ronaldo and Rooney, they are just amazing. I am not saying that other players of ManU are not talented or best. But they seem to play well when Rooney and Ronaldo are on the team and are lagging when they are not. ManU has lost a game and has earned just two points in three games and slowly its becoming difficult for it to keep the challenge. If it started repeating the same mistakes it has done in the previous three games then its future is at stake.
