The 22-year-old winger, who has 11 caps for Portugal and scored seven goals in 40 appearances in all competitions for Juventus last season, has signed a deal taking him up to 2030.

“Juventus announce that they have reached an agreement with FC Porto for the permanent acquisition of Francisco Conceicao,” Juve said in a statement released this evening.

Juventus, the only Italian club listed on the stock exchange, said it had paid “€30.4 million payable in four annual instalments”, in addition to €1.6 million in fees and other costs.

According to the Italian press, Juventus are also close to finalising the transfer of another player from Porto, Portuguese rightback Joao Mario while defender Alberto Costa is expected to go in the other direction.

Juve, now coached by Igor Tudor, have already strengthened their attacking line with the signing of Canadian international Jonathan David from French side Lille.
