1. Like others have stated, thats primarily because of City's form!
2. We had 34 points from 21 games where Rooney Started, 19 from the other 10. True. But 27 goals from 21 games and 12 from remaining 10 points that we score more with him than without him. ANd as far as points per game argument is concerned, without Rooney, we have faced comparatively weaker opposition- barring Arsenal(h), City(a), West Ham(h) and Pool(h). With him, Pool, City, Arsenal, Spurs, Chelsea twice, Leicester, Southampton.
