Robert Lewandowski returned from injury for Barcelona against Inter in the Champions League on Tuesday night, featuring as a late substitute at San Siro.
However, the game went to extra-time in Italy, meaning Lewandowski ended up playing more than was originally planned, according to Diario Sport.
The veteran also struggled to make any impact on the game, meaning Hansi Flick is yet to decide if he will start against Real Madrid on Sunday in El Clasico.
Sport note how Flick is “always very careful” with players returning from injury and so could use Ferran Torres once again or Dani Olmo as a false nine against Los Blancos.
