Valverde won't confirm who will be Barca's fourth midfielder at Chelsea
Andre Gomes and Paulinho are the most likely starters
Aleix Vidal is another option, as is Ousmane Dembele
Ernesto Valverde wouldn't give any clues to Chelsea on Monday as he was asked who would complete his midfield against the Blues at Stamford Bridge.
Paulinho started against Eibar on Saturday but the Brazilian faces competition for his place from, among others, Andre Gomes.
Asked about Paulinho and Gomes, Valverde said: "They're quite different, Paulinho and Andre. Andre is a player that can play in various positions. We have played him wider.
"Paulinho, menawile, plays more central, gets into the box. Both work hard and are good options ... but I won't give any clues about my team."
While Gomes and Paulinho are the most likely options, Valverde may also consider playing Aleix Vidal, as he did in the cup matches against Espanyol.
Ousmane Dembele, returning from his latest injury, is an outside bet, but it much more likely to start on the bench.
