Barcelona star misses training ahead of crunch Champions League clash with Porto
Marc-Andre ter Stegen was not present in Barcelona training on Monday and faces a race against time to prove his fitness ahead of Tuesday's Champions League clash with Porto. The goalkeeper withdrew from the Germany squad for this month's international break as he battled a back injury which also forced him to miss the weekend's 1-1 draw with Rayo Vallecano. Ter Stegen had hoped to return to action quickly, confirming on social media that he was "coming back soon", but it appears that comeback may not be imminent as manager Xavi revealed the goalkeeper is yet to return to training . "Tomorrow, Marc will have a fitness test," Xavi told the media. "We'll see how he is. "He hasn't trained, so tomorrow he will test to see if he is 100%." In Ter Stegen's place, Inaki Pena started against Vallecano and would likely retain his spot in the starting lineup against Porto. Ter Stegen has not trained / Mateusz Slodkowski/GettyImages LI...
