Messi has asked several times to sign Nicolás Tagliafico, also an Argentine, whom he thinks is an excellent player.
He has seen him in the Argentina team, and his experience in Europe has helped him a lot.
He thinks that bringing him to Barca would not cost more than 25 million euros.
Josep María Bartomeu knows Leo’s wish and will definitely consider it, but Barca would not be the only club that would try to buy the player.
