Barcelona are set to speak to Raphinha after the forward suffered another injury while with the Brazil squad and returned to his club.
Journalist Angel Perez reports that Barcelona want to understand why Raphinha has repeatedly sustained what appear to be almost identical injuries while on international duty.
The club are seeking details of Brazil’s warm-up routines and training methods as they investigate what may be causing the player’s muscle problems.
Raphinha has made an outstanding start to the new La Liga season after moving into a centre-forward role. He has scored 12 goals and provided three assists in seven league appearances.
The Brazil international has also scored twice in Barcelona’s 5-1 Champions League victory over Feyenoord.
