Marcus Rashford was Manchester United's hero with a dramatic extra-time victor that sealed a 3-2 aggregate victory over Anderlecht in the Europa League quarter-finals.
Mourinho remains frustrated by Martial's attitude and said: 'Do I think Anthony is a player with great potential? Yes.
United revitalised their season and blew open the English Premier League title race by sinking leaders Chelsea 2-0 on Sunday in a tactical masterclass by manager Jose Mourinho.
Jose Mourinho has challenged Anthony Martial to follow the example of Marcus Rashford at Manchester United, claiming the France global still needs to "do the things I want very well".
Despite Paul Pogba and Ander Herrera available as more "natural" choices to take corners and free-kicks, Mourinho has revealed he put Rashford on set piece duty because he can be "trusted" with them.
The Europa League was the competition in which Rashford made his senior breakthrough last season, scoring twice on debut against FC Midtjylland as an 18-year-old unknown. The same way I have to go in the direction of the players, the players have to come in my direction. Yes, I think. Can he play successfully for me?
It is not the first time Mourinho has expressed frustration about Martial after earlier this month criticising the forward, along with United's other attackers, for their toothlessness in the 0-0 draw with West Brom - the France international's last start.
United take on Anderlecht in their quarterfinal second leg at Old Trafford on Thursday.
"I am exhausted. I imagine the players are more exhausted than me".
"A lot of people will say things about me but I just keep my head down and work hard".
Manchester United drew the first leg of their Europa League quarter-final 1-1 against Anderlecht but it was still enough for the bookmakers to shorten their odds.
Mourinho does not seem to be thrilled with Anthony Martial this season, as he has only scored three goals all year in league play.
But from less than six yards out the world's most expensive player somehow managed to scoop his effort over the bar.
"Hopefully we have a semi-final coming up".
Winning the Europa League would guarantee a Champions League place, even if United finish outside the Premier League's top four. Mourinho is hoping to be able to call on Rooney's experience if need be: "With his experience and know-how of this knockout phase, he is a player who can be useful".
