Hertha Berlin defender Sebastian Langkamp is attracting Premier League interest.
The Sun says Leicester boss Claudio Ranieri wants more competition for Wes Morgan and Robert Huth.
He let Luis Hernandez join Malaga after failing to establish himself at the King Power Stadium.
Langkamp, 29, is on their radar. He has a long-term deal at Hertha but has been in and out of the side this season.
The Foxes are also trying to hijack Zenit St Petersburg's move for Chelsea's Branislav Ivanovic.
