Bayern confirmed earlier this month that Dier would not renew his contract. "We spoke with Eric about extending his stay, but he informed us he wishes to pursue a new challenge. He's been a fantastic professional," said Bayern's sporting director Christoph Freund.
Dier, who joined Bayern from Tottenham in January 2024, made 47 appearances, scoring three goals and providing one assist. He was crucial during Bayern's injury-hit season, starting their final 10 matches.
Monaco, chasing a Champions League spot, view Dier as vital to their defence. Their X account posted, "Eric Dier is Monegasque! His experience will elevate our squad. Welcome, Eric!"
Dier replied on X, "Excited for this new chapter with AS Monaco. Can't wait to help the team!"
Dier's move signals his intent to drive Monaco's domestic and European ambitions.
