He will be assessed today but looks likely to miss Saturday's pivotal title clash with Chelsea. The sight of him limping off sparked fears for South Africa, particularly as he suffered a metatarsal injury in the same foot four years ago almost to the day.United led through a 64-second Rooney goal but an equaliser from Franck Ribery - deflected in off Rooney - and a stoppage-time winner from Ivica Olic gave the German side victory.

We don't know how serious it is.'United sought to allay fears that Rooney had broken his foot again, though he left the Allianz Arena on crutches and with his right leg in a brace.
