Hit in the back, FC Barcelona goalkeeper Marc-André Ter Stegen is not in the Catalan club’s group for the reception of FC Porto on Tuesday (9:00 p.m.) during the 5th day of the Champions League.

The German goalkeeper has been unavailable since his return from the international break, where he felt pain in his lower back.

He will be replaced in goal by the inexperienced Inaki Pena, already starting against Rayo Vallecano in La Liga on Saturday (1-1) and who will play only his second Champions League match.

After a humiliating defeat against Shakhtar Donestk (1-0), Barça must bounce back against the Portuguese club to ensure they finish first in Group H.
