After five exhausting games in 15 days, Ernesto Valverde prepared for this second leg by fielding youth and fringe players against Huesca at the weekend. Gerard Piqué and Luis Suárez were suspended, while Sergio Busquets, Lionel Messi, Sergi Roberto and Ivan Rakitić were rested. Full-strength Barça against United? It's possible. Ousmane Dembélé is back, fit, and played in that Huesca match. Game on, and time for the Spanish champions to seal passage to the semi-finals.
Possible line-ups
Barcelona: Ter Stegen; Semedo, Piqué, Lenglet, Alba; Rakitić, Busquets, Arthur; Messi, Suárez, Dembélé
Out: Rafinha (knee)
Doubtful: Vermaelen (hamstring)
Misses next match if booked: Busquets, Semedo
Manchester United: De Gea; Dalot, Lindelöf, Smalling, Young; McTominay, Fred, Pogba; Rashford, Lukaku, Martial
Out: Bailly (concussion), Herrera (thigh), Shaw (suspended), Valencia (calf)
Misses next match if booked: Herrera, Matić, Valencia, Young
Key battle
Sergio Busquets v Paul Pogba: United have to score and they signed Paul Pogba for just these situations – however, Busquets helped keep him quiet in the first leg and has plenty of experience finishing off these ties against the best of oppositions.

Ernesto Valverde, Barcelona coach
There's no fear, just huge excitement. We're all aware that we have a very tough game ahead of us if we want to reach the semi-finals.
We're aware of Manchester United's strengths. We know we can't let it become a game with chance after chance; we have to close off any space. If they get space to run into, they're good. Obviously we'll try to stop them scoring and score ourselves. Our priority is to score, not to go out thinking we have an advantage.
Ole Gunnar Solskjær, Man. United manager
The 1999 final is a fantastic memory. The last time I was on the pitch here was the only time. I don't look back on that night too often; I'm just looking forward to seeing if we can play better against Barcelona. We are now 1-0 down at half-time, but if it is a game with many goals in it we stand a bigger chance.
If we keep a clean sheet, we're in the tie. We know we can score goals from set pieces – we're bigger than them – but we have to defend well. I don't mind if the goal comes in the 93rd minute. We have to be fitter and keep going.
