Busquets or even Digne in Pique's place if he isn't available for those Games and Vermaelen if he is ready.
Busquets? Engine of the team eliminated from the game. Rakitić is good, but still nowhere near Busi.
Digne? Bad defending in the last game + he could be also out for Valencia (broken finger).
Vermaelen will almost certainly not be ready, because he isn't even in training yet. We all know that he's made of glass, so playing him at 75% could cost us dearly.
Pique is apparently prepared to play through pain, but is it worth risking him to worsen his injury twoweeks before Chelsea (and of course with no other CB's except Mina avalible for Getafe).
Edit: Pique out until Eibar apparently (8-10 days). I guess our medical staff isn't taking any risks.
Mina-Umtiti and Mina-Costas/Busquets/Digne/Vermaelen it is then.
