Monaco manager Filipe Luis said caution was needed after Ansu Fati suffered an injury during the first half of the club’s 1-1 home draw with Lille.
The Spain forward was forced to leave the pitch in the 15th minute, having picked up the problem early in the match.
“Now, caution is needed,” Filipe Luis said when discussing Fati’s condition.
Fati has made three appearances in Ligue 1 this season but has yet to record a goal or an assist.
