Rashford sustained an ankle injury a few weeks ago.
The Man United boss will need every single one of his players on top form if they're to get past Barca and reach the semi-finals.
Sanchez had a long-term knee problem. "We know Manchester United are very risky and we have to play our best game to qualify". "He knows the game against PSG was not his greatest moment so he is only focused on playing well tomorrow against Barcelona". They have momentum, which is more than can be said of the team they will meet in Manchester.
"I remember Ole as a great team-mate - when I arrived here I was 17, I was very young, he was one of the older players", he said.
Pique, who spent four years at United as a youngster, returns to Old Trafford this week for the first time since moving back to Barca in 2008. He couldn't join the boxes which is the fun part of training, let's see tomorrow.
"It was a great experience playing alongside him".
The two ways I think United can hurt their opponents are with their pace on the break - Barcelona are susceptible to being surprised with a counter-attack - and at set-pieces.
Manchester United never know when they are beaten and must not be underestimated by Barcelona in the Champions League, says Gerard Pique. "I was injured or just coming back from being injured for the first game [against PSG], so it was nice to be able to test yourself against the best, and I think PSG are one of the best teams in the world". If you can beat them [by] scoring a lot of goals, you have to do it.
"We weren't lucky with the ref against PSG where they should have had a man sent off so we hope for some luck there as well".
