Pogba's long-term future at Old Trafford has been thrown into doubt after he was said to have fallen out with United chief Jose Mourinho.
However, United cannot afford to lose on Sunday as a defeat could most definitively drag them down to a scrap for fourth. Against Barcelona it was also a great performance from the team, almost ideal.
"These are different circumstances because many times they were matches for the title, this time we have both, us and them, that it is not the case, but we both play for top four and it is a big game independent of what is at stake".
The difference in performance against Sevilla would have been manifold if Pogba had somebody else in midfield willing to move the ball forward, to take risks with the ball, and supporters will be desperate to see Mourinho sign someone capable of doing just that once the window opens.More news: Mercedes' Lewis Hamilton, Valtteri Bottas Help Launch New W09 for 2018

"I don't want to speak about it". I know the kind of qualities that are really going to make a good player.
"If we win, we are happy, but then there are 10 games to go". The Brazilian put in an exceptional performance on Tuesday night, using his pace and strength against Barcelona. Every coach has to find the right way to manage him.
Willian is likely to keep his place though after scoring and also hitting the woodwork twice against the Catalan giants.
Liverpool and Man City are the only sides to take more points away from home than Chelsea this season. Yet, that one win came less than a year ago.
