Messi joins Argentina training at Real Madrid's training base
On Saturday he was unable to train with his international teammates
Barcelona forward Lionel Messi, who missed Argentina's first training session in Madrid on Saturday, returned to work on training at Real Madrid's Alfredo Di Stéfano stadium.
Messi, who didn't play in Argentina's 2-0 win against Italy in Manchester on Friday, has been struggling with a slight hamstring problem.
"I have been suffering from this hamstring injury for some time," Messi told TyC Sports before the game against Italy, which was settled with goals from Ever Banega and Manuel Lanzini.
"I always want to play but the road to the World Cup is still long. We decided to wait for this game [against Italy] to rest but I'm optimistic about playing against Spain [on Tuesday]."
Zenit Saint Petersburg's Leandro Paredes and West Ham's Lanzini did not train, though.
The three goalkeepers in the squad -- Sergio Romero (Manchester United), Willy Cabellero (Chelsea) and Nahuel Guzmán (Tigres) -- took part in a specific session.
The Argentine national team are based at Valdebebas in preparation for the game against Spain at Atletico Madrid's Wanda Metropolitano on Tuesday.
