It does sound like a lot of balls, but if there is an investigation I highly doubt Interpol would get involved for no good reason.
People saying, one player cant control the outcome and throw away a 4 goal lead. Its betting irregularties mentioned. Rosicky wanting Arsenal to win, as an Arsenal player would.
Plenty of ways to make money without losing the match or dropping points. How do we know there wasnt alot of money bet on Arsenal to conceed 2 or 3 goals in 2nd half, irregardless of the final result. Bribing in Phil Dowd, 2 penalties given, Rosicky playing Best onside, then giving the penalty away after it was disallowed. Im just theorising here of course, but its possible. Dare say the odds of the match ending a draw would be shorter than Arsenal to win but conceeding 3 min including pens.
