The former Boca Juniors goalkeeper believes that Messi will not be able to hold the title of football’s greatest ever player unless he proves himself at another club.
The retired keeper also referenced Messi’s relative lack of success on the international stage, with the forward and Argentina falling at the final hurdle at the 2014 World Cup in Brazil.
“It seems as if I am anti-Argentine, but until Messi performs in the big games, he will continue to be a player of home games,” Gatti said on TV show ‘El Chiringuito de Jugones’.
“He has to have balls to go to Real Madrid and prove everything there like Cristiano [did]. Otherwise he will be just one more [player].
“Cristiano went to the best club in the world. Messi plays at home, on his pitch with everything [that comes with that in terms of home comforts].
“Let him perform in the Champions League and the World Cup, otherwise he will always be one more [player]. When he performs there, he will fight with [Johan] Cruyff, Maradona and Pele.
“Messi performs when they let him perform. It’s very easy to perform with everything in your favour at home.”
Messi, now 32 years old, has won a record five Ballons d’Or alongside Ronaldo, scoring 608 goals and recording 247 assists in 695 appearances for Barcelona across all competitions in his career, claiming the top scorer award in La Liga five times and winning it six times in the Champions League.
He has won La Liga 10 times and the Champions League on four occasions but has failed to win a major trophy with Argentina despite netting 68 goals and registering 44 assists in 136 games for his country.
