Manchester United play Arsenal in what seems to be a vital fixture for both teams, who are still fighting for a Champions League spot. Here are some pre-match talking points for this fixture:

Mourinho's team selection

With the Europa league semi-finals set to be played at Old Trafford on the 11th of May, much talk has been placed on whether Mourinho will choose a strong line-up against Arsenal; which seemingly is a must-win for Mourinho and for fans alike. United, however, will welcome the return of Paul Pogba and Chris Smalling to the squad; who both featured in the first leg Europa League semi-final against Celta Vigo.

Luke Shaw, Phil Jones, Marcus Rojo and Zlatan Ibrahimovic, however, are all still out.

What will Rashford's role be on Sunday?

Despite his age, the young striker has already earned plaudits for his role in the team, which was highlighted during the semi-final game against Celta Vigo where the 19-year-old emphatically put away an audacious free kick to give United the advantage. However with the second leg of the semi-finals just four days after the Arsenal game, does this mean the striker will be rested or will Mourinho call up the young striker?

Will Ozil show?

Heavy criticism has been placed on the German attacking midfielder this season, mainly directed at his lack of commitment and intensity during big games.

Even Arsene Wenger has recently criticised the midfielders mentality after Arsenal's 2-0 defeat to North London Rivals Tottenham, as he was quoted saying on SkySports: "I don't know, I'm not sure (if he can cope with that responsibility). I think he embraces the challenge to play big games. Does he embrace the challenge to be criticised?

I'm not sure. Does he like to be criticised? I'm not sure."\

Despite this, Ozil is still regarded as a world class player by many and has all the capabilities to dictate matches, so it'll have to be seen which Ozil will turn up against United on Sunday.

Final Old Trafford visit for Wenger?

Rumours are still in the air over whether longtime Arsenal manager will stay beyond the current season, with his current contract set the end during the summer.

While fans have protested their disapproval of the Frenchmen for a number of seasons, Wenger's future at the club has not been indicated to any player or fans alike; leading to questions of whether this will be the last time Wenger steps foot into Old Trafford as the manager of Arsenal.
