No fee was disclosed, but British media reported that West Ham were paying around £20 million ($27 million) for the 25-year-old Denmark international.

Hermansen made 72 appearances for Leicester, winning the Championship title in 2024. He impressed last season as the Foxes were relegated from the Premier League.

West Ham were in the hunt for a new goalkeeper after Poland's Lukasz Fabianski left at the end of last season. Hermansen will compete with Alphonse Areola, 32, who played 26 times in the Premier League last season.

Casper Ankergren, who worked with Hermansen at Brondby, is West Ham's goalkeeping coach under manager Graham Potter. "I've heard a lot of great things about the club," Hermansen told the Hammers' website.

"I played West Ham twice last season, and playing at London Stadium was a great experience. It's an amazing stadium with loud, passionate fans. It's what you dream of as a footballer, and I can't wait to play in front of 62,500 fans as a West Ham player."

"The fans can expect me to be brave and bring good energy to help the team in the best way I can. This is a great step in my career."

Potter welcomed Hermansen to east London: "Mads has proved his quality at Leicester City with two impressive campaigns on a personal level over the last couple of years, and the exciting thing is that we feel his best years are still ahead of him."
