Sport revealed that the Argentine playmaker, who scored both goals in the Bernabeu including an astounding individual effort to put the Cules one step away from the final, was in some discomfort after the match and was checked by medical staff.
The doctors discovered a micro-tear as well as several areas of bruising, product of a brutal encounter with Jose Mourinho’s men.
The 23-year-oll will definitely be ruled out of Saturday’s clash with Real Sociedad, and will be wrapped in cotton wool by Barcelona to give him the best chance of making the second-leg in the Camp Nou.
Indications are that he should play against the Merengues, although with a two-goal cushion the temptation will be for the club to rest or bench him to ensure the injury is not aggravated for a potential final against Schalke or Manchester United.
