Booing could be heard from United fans every time Fellaini contributed from the moment he was brought on as a substitute at Old Trafford by new manager and star attraction for the day, Louis van Gaal.
But the Belgian international had the last laugh, securing a stoppage-time victory for the home crowd.

IT IS CONFIRMED. Louis van Gaal is a miracle worker. Fellaini scored the winner in front of Stretford End.

Fellaini paid back a huge chunk of that £27m fee with his winner against Valencia tonight.

It was nice to see fans cheer every time Fellaini touched the ball. The lad needs confidence.
