The 20-year-old has caught the eye during a loan spell with La Liga outfit Girona this season and, according to Spanish publication Don Balon, Messi has asked Nou Camp chiefs to launch a move for his signature.
Maffeo caught the Barcelona superstar’s attention when he impressively man marked him in a league clash last September. 
Messi struggled to influence the 3-0 win and was so impressed that he began talking to Maffeo midway through the game. 

“He asked me how old I was and if I was a Manchester City fan,” the City loanee said after the match.

“It is very kind (to say that).”

He added: “I had to mark him and I had to be close to him and not watch the ball.

“I appreciate the trust the coach placed in me.”
Maffeo joined City from Espanyol in 2015 but moved back to Spain on loan to Girona last season after making only a handful of appearances.
He has featured 20 times in all competitions for Girona this season and is also capable of playing on the right-hand side of midfield.
