McLeish has also selected three more uncapped players, as well as McTominay - Millwall goalkeeper Jordan Archer, Rangers winger Jamie Murphy and Fulham midfielder Kevin McDonald.
"He doesn't have to (speak to me)", the forward said.
"It's a special match because we can reach the quarter-finals", Montella admitted in the pre-match press conference.
Marcus Rashford actually kept Martial out of the side following the Manchester derby but his erratic running at Bristol City and those inexplicable choices on the counter-attack at Leicester relegated him back to the bench.
Even though Manchester United are in second place in the Premier League, and they are on the verge of advancing in the Champions League, pundits do not consider United to be elite. We don't ignore the goals we conceded, but you would say, 'OK, that's how you have to play.' We had these things in pretty much all moments, but we didn't score. I say ideal in relation to what the game gave us in the first half, it gave us the opportunity to be aggressive, direct, fast, intense and to score goals.
"If we go through to the quarterfinal draw - doesn't matter the opponent - it will always be one of the big names in European football, but we will try".
"In training is where I'm doing most of my learning".
Paul Pogba is a doubt for this game after he missed the victory against Liverpool due to a thigh injury picked up in training.
"Arsenal put up stats inside the dressing room after every game showing kilometres run, the passing etc".
"Just because City are having a successful season doesn't mean United's season has to be a disaster". Of course, Marcus - I have to be honest and give the credit to the people of the Academy that was responsible for his formation. "I still see myself as a player - for now anyway - and I am still enjoying training and being out with the boys".
They might be a distant second to City but the 56 goals scored in 30 games is already more than they netted in the whole of last season. Does he play every match from the start? No. "For me, the performance is globality and I'm really happy with Marcus". In the Champions League, the team has a slight edge ahead of this game since the first leg ended with a scoreless draw.
"Today, a big game, probably he didn't expect it, but we trusted him and thought the game adapted to his qualities".
Chelsea came from behind to win against Atletico in Madrid earlier in the season but Barcelona have won 23 Champions League ties against English opposition and I think, unfortunately, they will add to that tally at the Camp Nou.
