Former Manchester United midfielder Paul Scholes believes it will take another two years for Jose Mourinho to form a side capable of challenging for major honours.
United's underwhelming start to the season continued on Thursday night with a disappointing 2-1 defeat to Fenerbahce in the Europa League.
The Red Devils are now at serious risk of failing to make the knock-out stage of the competition, despite spending £145million this summer, and Scholes expects to see drastic changes in personnel over the course of the next two seasons.
'It's been quite a painful three years really and I think the next 18 months to two years could be similar until this manager has three or four transfer windows to really get a team that he wants,' Scholes told BT Sport.
