Barcelona already have an injury-hit squad, and the last thing Xavi will want to hear is a fresh injury to any of his senior players.
Joao Felix looked like he suffered an injury in the Champions League clash against Shakhtar Donetsk, and had to be subbed off.
The Portuguese was forced to leave the pitch in the second half, with nearly 20 minutes left of action.
Felix however calmed all fears after the game, as he insisted that he was fine.
“I’m fine! It was just a blow! Recovering and preparing for the next game,” Joao Felix wrote on Instagram.
Joao should be able to feature in the El Clasico on Saturday, October 28.
