Porto yet to bid for Gimenez

FC Porto is interested in AC Milan striker Santiago Gimenez but has yet to make an offer, per ESPN.

Gimenez has struggled in Italy since his move from Feyenoord and appears on his way out after a year and a half.

The Mexico international could be heading for Portugal, but a deal is still a ways off.

USMNT center back Mark McKenzie is returning to the Philadelphia Union, per The Athletic.

The Union will pay around $2.5 million to land McKenzie from French side Toulouse. The 27-year-old will move back to MLS in the winter, spending the first half of the 2026-27 season in Ligue 1.

McKenzie joined Belgian side Genk in 2021 after developing in the Union’s academy.

Sporting Kansas City has signed Brazilian winger Andre Luiz from Greek side Olympiacos.

The MLS side paid a reported $18 million fee for the 24-year-old, smashing the club’s record fee.
