Leicester City boss Claudio Ranieri has declared any unhappy players can go in the January transfer window.
Leonardo Ulloa, Jeffrey Schlupp and Bartosz Kaputska are the most likely candidates to leave the Premier League champions when the window opens next month.
Striker Ulloa, 30, cost £7million from Brighton in 2014, left-sided utility man Schlupp, 23, came through the ranks and Poland midfielder Kaputska, 19, was brought in for £2m last summer.
Hamburg-born Schlupp was the subject of a failed £10m bid from West Brom in the summer but the Baggies have retained their interest in the player, who has made 140 appearances for the Foxes.
