The former Barcelona man faces a long spell on the sidelines after being hospitalised on Tuesday, but his coach is concerned about the emotional toll
Marc Bartra is expected to return to action in four weeks after he was injured in the attack on Borussia Dortmund's team bus but coach Thomas Tuchel fears the team's mental recovery could take much longer.
Three explosions occurred while the BVB bus was making its way to Signal Iduna Park for their Champions League quarter-final, first-leg tie against Monaco, with the match eventually postponed to Wednesday.
Bartra required surgery on his right wrist, but stands a chance of returning before the end of the season.
