Barcelona has held opening talks with the 32-year-old Manchester City striker agents over a free transfer this summer. Given the good relationship between Messi and Aguero, the Catalan giants are hoping to persuade the captain to extend his contract with the club.
Sergio Aguero, the Citizens' record goalscorer with 258 goals in 387 appearances, will leave the Etihad Stadium at the end of the season.
Spanish football expert Alvaro Montero toldSky Sports
, Lionel Messi could be convinced to stay at Barcelona if the club sign Sergio Aguero this summer.
"It is a huge possibility as far as we know. Sergio Aguero has a desire [to play] for Barcelona. There is no catch. He is 32 years old. He knows perfectly the language, he knows La Liga, he knows the country and one of his best friends in football is Lionel Messi. It is said in Barcelona, Catalonia that there is a huge possibility for Joan Laporta (Barcelona president) to try and convince Messi to stay by signing one of his good friends Sergio Aguero after Luis Suarez left the club last year.
"In the last weeks and last months we have seen Messi more committed and comfortable. He is even fine with Ronald Koeman. We have seen him laughing in the games, winning the Cope del Rey. Now they are in the battle for the La Liga title and although many people said that he could go to Paris Saint-Germain, in my point of view Joan Laporta could be the key.
"Sergio Aguero can be one of the reasons for Messi to stay as Barca needs a striker, goals and needs a better sports project for the future to try to win for example the Cope del Rey, maybe La Liga and especially the Champions League which they have not won since 2015."
