Arsenal boss Arsene Wenger shrugged off Manchester United's 4-0 thumping of AC Milan.

England striker Wayne Rooney continued his fine form with a brace as the Italians were swept aside, losing 7-2 on aggregate.

Wenger, however, feels United's first-leg victory in Milan had done the real damage.

"It was not a surprise," the Arsenal manager said.

"Last night's game was never in doubt after the first leg, which put Milan in a position where they had to chase, go on a big gamble in the second leg, and of course Manchester United punished them.

"The decider was in the first game. In the heads of Milan, it was already all over."
