Barcelona v Manchester United (1-0) team news
Romelu Lukaku is expected to return for Manchester United and lead a three-man front-line against Barcelona.
Ashley Young is expected to play at right back with winger Diego Dalot dropping back to the left back position for the travelling Red Devils.
Nemanja Matic and Alexis Sanchez have travelled with the team but are likely to take a seat on the United bench.
The midfield trio of Fred, Scott McTominay and Paul Pogba have shown some promise with each player bringing something different to the party for United.
Thomas Vermaelen has yet to recover from a longterm hamstring injury and Rafinha’s knee is a long way from healed but Barcelona have few injury concerns in comparison to their opponents.
Ousmane Dembele will make his long-awaited return, his pace could provide Manchester United’s defence with a formidable challenge.

Juventus v Ajax (1-1) team news
Juventus head into the clash fresh off a Serie A upset loss and Massimiliano Allegri was in no mood to give away his team selection.
“There was already a chance that Mario Mandzukic wouldn’t play [on Tuesday],” Allegri said.
“I still need to decide who starts in attack. It could be Paulo Dybala or Moise Kean or neither of them.
“If one of them plays, then one of Mattia de Sciglio and [Joao] Cancelo will be left out. It depends on what I decide to go with tomorrow night.
“Cristiano has extraordinary quality. In certain moments he becomes an unstoppable player and you can see it on his face.
“Alex Sandro will play [on Tuesday]. [Leonardo] Spinazzola has done well but he needs to get used to these types of games, which take away a lot of your physical and mental energy.
“If Dybala plays then he will wear the captain’s armband, otherwise it will be Bonucci.
“Douglas Costa isn’t in perfect condition right now. Hopefully in tomorrow’s final training he can show me that he has at least 30 minutes in his legs, because he can be decisive.”
Longterm injury absentee Hassan Bande and suspended Nicolás Tagliafico are the only players ruled out of contention for Ajax’s match XI. Frenkie De Jong is expected to shrug off a hamstring niggle to take the field in Turin.
Juventus: Szczęsny; Cancelo, Bonucci, Rugani, Alex Sandro; Emre Can, Pjanić, Matuidi; Bernardeschi; Kean, Ronaldo
Out: Mandžukić (knee), Chiellini (calf), Cáceres (thigh), Perin (shoulder)
Doubtful: Douglas Costa (thigh)
Misses next match if booked: Bernardeschi, Matuidi
Ajax: Onana; Veltman, Blind, De Ligt, Mazraoui; De Jong, Van de Beek, Schöne; Neres, Tadić, Ziyech
Doubtful: De Jong (hamstring)
Out: Bandé (calf), Tagliafico (suspended)
Misses next match if booked: Blind, De Jong, De Ligt, Schöne, Van de Beek, Ziyech.
