Roy Keane has named the Manchester United player who he doesn't trust to start matches.
The individual made a significant impact after coming off the bench as United beat Leicester 2-1 in the FA Cup fourth round on Friday night.
However, former United star Keane believes that the player is better suited to featuring as a substitute at present.
Keane's fellow ITV pundit Ian Wright admitted that he was surprised that United boss Ruben Amorim didn't start the player against Leicester.
Leicester took the lead at Old Trafford through a goal from Bobby De Cordova-Reid just before half time.
