Manchester United manager Jose Mourinho has once again told Anthony Martial that he must improve if he is to work his way back into the starting lineup on a regular basis.

The 21-year-old was not included in the squad for recent trips to face Stoke City and Hull City, but returned to the starting lineup for the 4-0 FA Cup rout of Wigan Athletic at the weekend.

However, Mourinho stressed that the Frenchman has a lot of competition for his place and hinted that he would not make the side for Wednesday's visit of Hull in the Premier League.

"He has to perform better than the others who are competing for the same positions [if he wants to start]," he told reporters.

"His position is one where we have lots of options. Do you want me to leave [Henrikh] Mkhitaryan out after being man of the match and playing so well as he did? I can't.

"The players pick themselves. I am just there to analyse what they do and try to be fair with them. Such a good performance, Mkhitaryan has to play tomorrow. Simple."

Martial has scored just two goals in 13 Premier League appearances for United so far this season.
