AC Milan have signed midfielder Tijjani Reijnders from Dutch club AZ Alkmaar on a five-year contract, until 2028, the Serie A club announced on Wednesday.

No financial details were disclosed, but Italian media reported that Milan paid a sum of around €20m with add-ons.

Last season, the Dutchman excelled for AZ, scoring seven goals and providing 12 assists in 54 appearances in all competitions.

He will be manager Stefano Pioli’s fifth signing during this transfer window, following Marco Sportiello, Luka Romero, Ruben Loftus-Cheek and Christian Pulisic, who arrived at San Siro.

Pioli has bolstered the midfield this season by adding Reijnders, 24, to the squad to fill the void left by Sandro Tonali’s departure to Newcastle United at the start of July.

Reijnders was first called up to the national team during the Netherlands Nations League Final Four campaign in June, but he hasn’t played a game.
