Spurs have reportedly made their interest in the youngster official by tabling a bid of 11.5 million euros for Clarke.
However, the 'Daily Mirror' have reported that Leeds were not impressed by Spurs' initial offer, and instead want the North London club to pay 24 million for the 18 year-old.
Clarke is under contract at Leeds until 2021, and the Yorkshire outfit are confident in retaining the services of their starlet despite Tottenham's interest.
He has featured 22 times for Leeds this year, starting 4 times and scoring 2 goals.
