Leo Messi already knows the date of his return. He will be available to play against Real Madrid next 21st November, according to reports by Mundo Deportivo and Sport this Sunday.
Messi will be about 7 to 8 weeks sidelined, more 7 than 8, so he will be available for Luis Enrique for El Clasico. However, it will be the first match he plays since the injury, so maybe he can't play the full match.
This morning has been the first traning session at Barcelona's Sports City without Leo Messi.
