Tottenham Hotspur are in danger of being priced out of the race to sign Leandro Damiao.
Spurs boss Harry Redknapp is known to be an admirer of the Brazilian international, with two bids already registered and rejected for the 22-year-old striker.
Competition comes in the shape of Barcelona for the player's signature, with Juventus and Fiorentina also thought to be keen on the Internacional forward.
Original valuations during the summer suggested Tottenham Hotspur would need to pay in the region of €22 million to secure Damiao's signature, but that figure now appears to have sky-rocketed.
"Damiao is proving to be worth the amount specified in his termination clause," said Internacional vice-president Luis Anapa, referring to a €50 million release fee in the player's contract.
"And with how he is playing I am sure there will be a club willing to pay the amount requested."
Spurs were linked with a handful of players in the position during the summer transfer window, with Redknapp failing to land any of his attacking targets in a frustrating final week during the transfer window.
With Peter Crouch also leaving the club, Tottenham Hotspur are still looking to strengthen their forward line at the next possible opportunity, although Damiao might now be beyond their financial capabilities.
