He told reporters after the game:
"Van Persie has a knee problem and we don't know whether it was a twist or a kick. We will have to wait for 24 hours but I believe it is more of a kick after seeing how it happened, so I'm not too pessimistic.
"Jose Reyes got a kick on his knee, while Thierry Henry got an Achilles problem. At half-time, we had two players who were not certain to come back out.
"Thierry can't walk very well so we will have to wait until Friday or Saturday to see if he can play at Liverpool on Sunday."
