Casemiro will be available fresh for the game against Barcelona it will be the first game since he left La Liga against a Spanish side
Rashford should just be in the right position so he can always score those goals
Garnacho and Sancho can both come up at the wings to create chances
With this combination things looking amazing for the Manchester United in first leg of this round which is going to be play at Barcelona and Casemiro and Rashford both are key players for them with this deadly combination they already achieve good successes if they are able to handle this all and having something positive then surely things could be at the top for the Manchester United in long run for their success in Premier League and next year's Champions League because right now they are having fair chance for staying into top four and having good results in all other three competitions which are they involved and doing good job under Erik ten Hag in this season after having poor start.
We all can't wait for the Manchester United vs. Barcelona game. It's true that Manchester United has had a lot of success thus far because to the chemistry between players like Casemiro and Rashford. Following their impresive showing in the Premier League and other tournaments this season under Erik ten Hag, this match promises to be a good one to watch. It's unfortunate, however, that these two formidable squads will clash so early in the competition. Both of them making a significant influence during the tournament would have been fantastic. But, unfortunately, one team must go home since that's just how games work. My gut tells me that Barcelona will win, but it's a close game. Their defense is too strong.
