After arriving in Munich from Tottenham Hotspur in January 2024 - initially on loan - Dier made his move permanent with a one-year contract. But under new manager Vincent Kompany, the 31-year-old found consistent minutes hard to come by. Across all competitions, Dier featured in just 25 games, starting 16 times.
Despite the limited role, Dier could exit Germany with a major career milestone - his first piece of silverware. Bayern are on the cusp of clinching the Bundesliga title, needing just one more win - against RB Leipzig - to seal it.
"We had conversations with Eric about a new deal," said Bayern's sporting director Christoph Freund. "But he's decided to move on. He's a fantastic professional and a great person-we wish him nothing but success."
Dier's move to Monaco represents not just a change in scenery but potentially a new lease on his career. After years as a dependable if under-the-radar figure at Spurs, he now has the opportunity to re-establish himself as a key player in one of Europe's top leagues.
Meanwhile, his Bayern teammate and fellow former Spur, Harry Kane, is also on the brink of breaking his own silverware drought - though he'll miss the decisive Leipzig match due to suspension.
