The Portuguese gaffer, however, revealed that Zlatan Ibrahimovic who missed United’s 1-0 FA Cup quarter-final loss to Chelsea on Monday night will make a return for the game.
Mourinho at a press conference on Wednesday said that, “He [Martial] was injured for Chelsea match.
“If you are injured for the Monday night then you are injured for the Tuesday morning session training session, and then you cannot play on Thursday. So Martial is out of my mind.
“Rooney had a kick in his knee area. We have the same players we had in the last match plus Ibrahimovic returning to the Europa League.”
He added that despite United holding the Russian side to a 1-1 away draw, the tie is far from over.
He said, “We know that the 1-1 result leaves everything open. We know Rostov is a very good team. We are so many matches away and some of those are against big opponents who have experience in the Champions League.
“1-1 is a very doubtful result. Tomorrow we go with everything that we have, the fans will give us a little bit of extra energy.
“Tomorrow we believe we can cope with the situation and reach the quarter-final.”
