"From what I have seen, the fans in Melbourne are not only the best in the league but they rival the atmosphere in Europe and I'm looking forward to being a part of that on the field in a Victory shirt and playing for them this season," Nani said.
"We're proud to be able to recruit a player like Nani to our club and believe he will be an incredible asset for Melbourne Victory and the entire A-League," an excited Popovic said.
The arrival of a storied player, even one in the tail end of his career, is a boost to the ALM competition after a 2021-22 campaign where crowd numbers plummeted.
Australian Professional Leagues chief executive Danny Townsend said in May the competition wanted clubs to look at "sugar hit" marquee names in a bid to boost the league's flagging profile.
"I look at marquee players as 'bums on seats' players ... marquees are genuine world class stars and our game needs it," Townsend said at Western United's pre-finals function.
"It gets criticised historically as being a bit of a sugar hit -- our game needs a sugar hit."
