Barcelona will face Borussia Dortmund at Signal Iduna Park on Tuesday night, with the Blaugrana able to welcome Luis Suarez back into the starting line-up after his return from injury.
The Uruguayan came on against Valencia at the weekend and scored two goals in a 5-2 win, and he now seems set to start alongside Antoine Griezmann and likely Sergi Roberto in attack.
It is not guaranteed that Sergi Roberto will start, but Dortmund away in a Champions League opener may not be the right setting for a 16-year-old Ansu Fati to retain his place in the side.
The notable name on Barcelona's bench will be Lionel Messi, who is yet to play a minute of football since injuring his calf on his first day back for pre-season. The Argentine could play a part in the match in the second half.
For Dortmund, they have Real Madrid defender Achraf Hakimi on loan while there will be a Barcelona reunion for Paco Alcacer.
A couple of the names to note for the Germans are Jadon Sancho and Marco Reus, while the leadership of Mats Hummels at the back is likely to be a key factor in the match.
Borussia Dortmund's probable line-up: Roman Burki; Achraf Hakimi, Manuel Akanji, Mats Hummels, Raphael Guerreiro; Axel Witsel, Thomas Delaney; Jadon Sancho, Marco Reus, Julian Brandt; Paco Alcacer.
Borussia Dortmund's bench options: Marwin Hitz, Lukasz Piszczek, Dan-Axel Zagadou, Julian Weigl, Mahmoud Dahoud, Thorgan Hazard, Mario Gotze.
Barcelona's probable line-up: Marc-Andre ter Stegen; Nelson Semedo, Gerard Pique, Clement Lenglet, Jordi Alba; Ivan Rakitic, Sergio Busquets, Frenkie de Jong; Sergi Roberto, Luis Suarez, Antoine Griezmann.
Barcelona's bench options: Neto, Jean-Clair Todibo, Junior Firpo, Arthur Melo, Carles Alena, Arturo Vidal, Carles Perez, Ansu Fati, Lionel Messi.
