Delightful control of a high ball from Giggs but his eventual cross from the left is blocked.

Rooney's corner from the left eludes everyone but Jones retrieves. Only to swing the ball out of play from the right himself.

Lengthy spell of Fulham stroking it around ends when Riise loses the ball allowing Nani to run in on goal but Schwarzer smothers his near-post effort.
