Former Portugal international midfielder Deco has hailed Inter Milan's new signing, Joao Mario, claiming the 23-year-old could ply his trade at any club in the world.
Mario was an ever-present figure in Fernando Santos' Portugal side as they clinched the 2016 European Championship, which led to him completing a move to Inter after a decade-long stay at Portuguese club Sporting Lisbon.
"I think he is [a good signing] as Inter are trying to rebuild," Deco told Omnisport.
"Obviously, Joao Mario can be a player that helps a lot in this process for the club. It is a great club.
"Joao Mario, for me, is a player who could play for any club in the world; Barcelona, Real Madrid, Inter, [AC] Milan, Bayern [Munich]," he concluded.
Mario represented Portugal at various youth levels before making the step up to the senior side in 2014. To date, the 23-year-old has made 22 appearances for the senior national side.
