under premier league rules, the opposition is allowed access to any part of the pitch at any time after a match, so the groundsman wasn't doing his job
Maybe the whole thing was planned? Say the groundsman was meant to entice Evra into a fight and subsequently unsettle the whole club before a Champions League semi-final and title run in. Notice how no Chelsea players were involved whatsoever. There were what, 6 or 7 Man Utd players out there and this whole story does not affect Chelsea players or Avram Grant at all. I reckon Chelsea would have rather played Barcelona in the final.
We don't know what Abramovich is capable of, and I wouldn't put this past him.

The Chelsea board put their heads together and this is what they came up with? Roman is evidently not capable of much intrigue at all.
I would've tried to hook (the other) Ronaldo up with some transvestites.
But that's just me.
