After being left on the bench for Saturday's 4-1 win over Fulham, the midfielder has been warned to get on the same level as the rest of the team
Jose Mourinho has warned Paul Pogba that he must adopt the same mentality as his Manchester United team-mates and challenged him to show "how good he is" against Valencia on Wednesday.
The midfielder was an unused substitute on Saturday as United beat Fulham 4-1 at Old Trafford to bring an end to their four-game winless run in the Premier League.
It is the second game in a row the 25-year-old has been left out of the starting XI, having been limited to a 15-minute cameo against Arsenal in midweek.
