Are you his spokesman or what?
How do you know this? Did he say "Yeah i dont like Dybala and Icardi" in a interview?
He has just said that him and Dybala plays kinda the same style, which obv makes it a problem if they play together, but remember, he said this back in 2018, things change.
EDIT: Only thing i heard about Messi-Icardi is that Messi was angry at Icardi a few years ago since Icardi started dating Messis friends ex-wife, lol?
