Neymar does not have to leave Paris Saint-Germain to fulfill his goal of becoming the world's best player, according to Brazil team-mate Alisson. (More Football News)
The forward was strongly linked with a return to Barcelona during the transfer window, but no move to Camp Nou came to fruition.
Neymar has instead remained in the French capital, scoring four goals in five Ligue 1 games since recovering from a foot injury.
The 27-year-old did not finish in the top 10 for the 2018 Ballon d'Or but, asked if Neymar could become the best player in the world by joining Barcelona, Alisson told Mundo Deportivo: "I think that Neymar can be the best in the world on any team.
"Neymar is a high-level player and would be fundamental in any team in the world. If he returns to Barcelona or not... I wish him good luck and to play with his usual joy and energy, wherever he is."
Five-time Ballon d'Or winner Lionel Messi was reportedly pushing for Neymar to be signed by Barca, but he told RAC1 this month he was surprised his former team-mate did not join Real Madrid after it became clear he wanted to leave PSG.
Messi and Alisson met in the Champions League for the second season in a row last term, with the former Roma goalkeeper again coming out on top with a stunning second-leg comeback.
The Argentina captain had struck twice in the first leg to seemingly give Liverpool a mountain to climb but they won 4-0 at Anfield to overturn their deficit, going on to win the tournament by defeating fellow Premier League side Tottenham in the final.
Alisson also got the better of Messi at this year's Copa America, where Brazil beat Argentina 2-0 in the semi-finals before going on to lift the trophy on home soil with a win over Peru.
"The truth is that Messi played very well in the first leg in Barcelona and achieved two goals, but in the return I managed to stop him in some important moments," Alisson added.
"Messi is one of the best players in football history, but I don't think only of duels with him. Both Barcelona and Argentina are two very good teams that have high quality players.
"Luckily, in the last three matches I have been able to overcome him, but the merits are of the whole team: Rome, Liverpool and Brazil."
