Brazilian side Internacional have stated that they will only sell star forward Leandro Damiao for €50m (£43.8m).
A host of Europe's top clubs are reportedly interested in the 22-year-old, with Barcelona and Tottenham Hotspur considered the player’s most serious suitors.
Spurs had a bid for Damiao rejected at the start of the summer, while Barcelona have already made noises over a potential switch to the Nou Camp.
Damiao’s release clause stands at €50m, an amount Internacional are insisting must be paid for their starlet.
"Damiao is proving to be worth the amount specified in his termination clause," said Internacional vice-president Luis Anapa.
"And with how he is playing I am sure there will be a club willing to pay the amount requested."
The Brazilian has made four senior appearances at international level, scoring once.
