The 20-year-old centre-back has caught a lot of English interest, as Arsenal, Manchester City and Chelsea are all reportedly keen on winning his services.

However, Subotic's agent Steve Kelly said that it was Everton who made an official offer for his client, adding that Dortmund rejected the bid.

Subotic recently signed a new contract with the Black Yellows and the former Mainz man recently said that it will take a mega offer to lure him away from Dortmund.

Prior to playing for Mainz and Dortmund, Subotic played the University of South Florida team between 2004 and 2006.

Subotic featured for the American youth national sides when he moved with his family to the US in 1994 before making his senior national debut for his native Serbia last March.
