Benfica have taken 21 players to Switzerland for Matchweek 2 of the UEFA Champions League. The big news is the addition of 18-year-old goalkeeper Mile Svilar, and the return of of Eduardo Salvio after a sprained ankle.
Eliseu is included after being left out against Paços de Ferreira, but Lisandro López and Douglas remain out of favour. Filip Krovinović is unavailable, as he was not registered for European competition. Diogo Gonçalves has been dropped.

Midfielders: Fejsa, Filipe Augusto, Samaris, Živković, Salvio, Pizzi, Cervi and Rafa Silva
