FC Koln defender Timo Hubers is set to be a £6million target for Premier League clubs this summer.
Newcastle, Leeds and Crystal Palace are understood to be tracking the 25-year-old centre-back, while West Ham, Southampton and Championship promotion favourites Fulham are also monitoring his situation.
Hubers signed a two-year contract when he returned to the Bundesliga with Koln in July from second-tier Hannover 96, and will enter the final 12 months of his deal in the summer.
A 6ft 2in ball-playing defender, Hubers has made 18 appearances in all competitions this term as Koln have bounced back from finishing third-from-bottom last season to reach eighth place with six games left to play.
