Marouane Fellaini conceded Manchester United are going to find it difficult closing the gap on the Premier League's leading pack after drawing 1-1 with Wolves on Saturday.
Former manager Sir Alex Ferguson was in attendance at Old Trafford for the first time since suffering a brain haemorrhage in May and United were unable to secure a win.
Although Fred gave the hosts the lead against the run of play in the 18th minute , Wolves battled back and deservedly levelled just after the break – Joao Moutinho finding the top-left corner after good hold-up play by Raul Jimenez.
