Manchester United manager Jose Mourinho said Paul Pogba needs time to realize his full potential in England after the French midfielder scored twice in Thursday's 4-1 win over Fenerbahce.

Pogba, a world-record $109.1 million signing from Juventus, scored a penalty and converted a long-range effort in the Europa League group game at Old Trafford.

The 23-year-old is yet to hit the heights since returning to United after four years in Turin, but Mourinho believes performances like Thursday's will accelerate the process.
