United were leading 3-0 when James Morrison pulled one back for WBA before Romelu Lukaku came on to make it 3-2.

But Ferguson's team restored the three-goal lead as Javier Hernandez and Robin van Persie made it 5-2.

But the superb Lukaku hit two more goals as Youssouf Mulumbu scored to complete an incredible fightback against the famous comeback kings.
