Tottenham are closing in on the signing of Argentine striker sensation Jonathan Calleri, according to a report.

The 22-year-old, whose registration is held by an investment group even though he plays for Brazilian club Sao Paulo, is regarded as an emerging star in his homeland.

Yahoo! Brasil claim Calleri’s father Guillermo has informed Sao Paulo that Tottenham have reached an agreement to sign the forward this summer.

It is reported an offer from Spurs has been agreed and that the player will move to White Hart Lane when the Copa Libertadores is over.

This means he is set to complete a transfer to Tottenham in August.

Spurs would have to buy the registration outright from the investors, although the fee would represent good value for a striker in comparison with some of the price tags demanded for emerging Europe-based strikers.

Calleri will also be granted an Italian passport this summer – he qualifies via his grandparents – which will mean he can move to the Premier League without any need for a work permit.

Calleri hit the headlines last summer with a stunning rabona goal for former club Boca Juniors against Quilmes.

He has since been loaned to Sao Paulo for six months via a Uruguayan club and 10 matches for the Brazilian side have yielded an impressive eight goals.
