Wenger got sent off the field for kicking a water bottle.Van Persie’s last gasp goal had been ruled offside.Who wouldn’t have kicked a water bottle at that?In fact,in the light of all the frustration that preceded that offside call,all credit must be given to Wenger for only kicking a water bottle and not kicking anything else. But a self righteous rule book toting fourth official thought otherwise.He complained to the ref who then gave Wenger his marching orders.If ever there was a fourth official who needed to be kicked where it matters it was him (or do I mean he?).However Wenger restrained himself and moved off into the Man U portion of the stands in a dignified manner.This was also found unacceptable to the official and the farce continued till Wenger moved into an area that the rule book allowed water bottle kicking managers to stand in after they had been sent off.In the first half Arshavin was brought down in the penalty area-shortly before he scored that brilliant goal.The ref didn’t see anything that violated the rules and a legitimate penalty was denied.Not exactly a game where the officials covered themselves with glory for being impartial and accurate and objective in their decisions.
