AC Milan made Andre Silva their fourth summer signing on Monday, acquiring the Portugal striker in a €38 million deal with Porto.
Silva, 21, follows Mateo Musacchio, Franck Kessie and Ricardo Rodriguez in joining the Rossoneri, who now have reportedly spent over €99m on new recruits so far this summer, following their takeover by Chinese investors.
"Andre Silva joined us last night at Milanello, today he passed his medical and we can now officially consider him a Milan player," Milan's general manager Marco Fassone told the club's media channels. "I and [sporting director] Massimiliano Mirabelli are really satisfied to have convinced Andre and Porto so quickly.
"Andre's eyes displayed how much pleasure he has to wear our shirt."
Silva arrived in Milan on Sunday and, after a series of medicals and after agreeing personal terms, the Serie A club confirmed that he had signed a contract until 2022. He will now link up with Portugal on Monday night in preparation for the Confederations Cup.
"I'm very happy to have joined such a prestigious club with such a great history," Silva said. "I can guarantee I will give everything I can to help this club realise their ambitions."

Silva scored 16 goals in 32 appearances in the Portuguese Liga last season, adding a further four in eight Champions League outings. Capped eight times by his country, he has scored seven goals in those outings, including in Friday's 3-0 win over Latvia.
Porto confirmed the deal could increase to €40m with incentives, and said in a statement: "FC Porto wishes Andre Silva the greatest happiness and a lot of success on a personal and sporting level, without forgetting how he has always given everything for the club."
Silva will wear Milan's No. 10 jersey, which was left by the departing Keisuke Honda.
Milan will make their return to Europe next season by participating in the Europa League, after spending the past three seasons without European football. They were bought by the Chinese-backed Rossoneri Sport Investment Lux company in April and the new owners have shown their ambition with heavy investment in the squad this summer.
Silva is unlikely to be the last new arrival at the club this summer.
"We had promised that we would give coach Vincenzo Montella about two thirds of our squad for 2016-17 in time for preseason, and I think we are well on our way to doing that," Fassone added.
