According to the same article, Verratti is one of a number of big-name transfer targets being considered by Manchester United this summer.
Fred comments on rumours linking him with a move to Man United, while Brazil boss Tite urges him to solve his situation as quickly as possible.
Brazil midfielder Fred became Manchester United's first signing of the close season after they agreed a deal on Tuesday with Ukrainian outfit Shakhthar Donetsk.
"He is a wonderful player", the 46-year-old told Sky Sports News.
City were close to landing Fred in January, sources said, before Pep Guardiola turned his attention to Napoli's Italy worldwide Jorginho.
Brazil's Neymar to return from injury against Croatia
The defeat was Croatia's second in their last three friendly games (won one) ahead of the FIFA World Cup. Brazil will undoubtedly be careful with the 26-year-old, who is arguably their most important player.
United had been in the market for midfield reinforcements after seeing Michael Carrick head into retirement.
He is industrious, dynamic, energetic and possesses a wide array of technical qualities, which could make the Belo Horizonte born player the ideal foil for Nemanja Matic and Paul Pogba. The Shakhtar midfielder has cemented his place among Europe's elite at his position over the course of his stay at the Ukrainian outfit.
The article says that Mourinho watched Verratti in action during Italy's World Cup playoff defeat to Sweden at the Friends Arena in Stockholm past year.
The Selecao's opening match is against Switzerland on 17 June.
