Tottenham have seen a £10.5 million bid for Brazil striker Leandro Damiao rejected by Internacional.
Harry Redknapp is known to be looking to improve his attacking options this summer, after failing in a number of bids for front-men in the January transfer window and then subsequently seeing his existing options - including Jermain Defoe, Roman Pavlyuchenko and Peter Crouch - fail to fire in the second half of the season as Spurs missed out on Champions League qualification.
Damiao, 21, made his full debut for the Selecao in a friendly against Scotland at Emirates Stadium earlier this year, but is believed to have attracted interest from clubs including Roma, Benfica and Barcelona.
Internacional have now revealed that Spurs are the first club to make formal contact about the player - although they warned they will have to up their bid significantly if they are to get their man, who is valued at around £17 million.
They will also have to wait until the Brazilian season concludes to wrap up any deal..
"It was the first concrete offer we've had," club president Giovanni Luigi confirmed, when asked about Spurs' approach. "I said I didn't want to sell now, but I think they will come back with another attempt.
"I warned that he'll only leave at the end of the year and for more money."
