Jannik Vestergaard, 29, made 32 appearances in all competitions for Southampton last season; Denmark centre-back was previously subject of interest from Leicester manager Brendan Rodgers in January 2020; defender joins for £15m, signs three-year deal and can face Wolves on Saturday
Vestergaard was registered in time to be able to play against Wolves in Leicester’s season opener on Saturday.
The Foxes wanted to sign a centre-back after Wesley Fofana was ruled out for a significant period with a broken leg sustained in a pre-season friendly against Villarreal last week, while Jonny Evans is struggling with a long-term foot issue.
The Denmark international joined Southampton from Borussia Monchengladbach for a fee believed to be £18m in July 2018.
He made 32 appearances under Ralph Hasenhuttl last season as Southampton finished 15th in the Premier League and played in all six of Denmark’s games as they reached the semi-finals of Euro 2020.
