Bengaluru, February 10: Italian giants Inter Milan have beaten off competition from Real Madrid and Atletico Madrid to complete the signing of Lautaro Martinez, according to reports in Italy.

The Argentinian forward, 20, is considered one of the best young talents in his homeland and has been on the radar of top European clubs for quite some time now.

According to Gazzetta dello Sport reports, Inter, who have been looking at him for a while, have finally completed the deal for £17.6million plus add-ons - and have moved to ensure he will stay at San Siro for the long haul.

Martinez has signed a five-year deal worth £25,000-a-week, which will increase every 12 months.

While, they have slapped a £105m release clause on their newly-captured wonderkid, which is more than their current main star Mauro Icardi, whose fee is set at £97m.

Two Argentinian Inter Milan legends were key in working together to secure the deal ahead of the two La Liga heavyweights. San Siro vice-president Javier Zanetti worked with Racing Club technical director Diego Milito to finalise the transfer.

Martinez has shot to prominence in his homeland, with some superb performances over the past two seasons.

This term, he has scored seven goals in eight matches - including a hat-trick in Monday's 4-0 victory over Huracan and is a contender for Argentina's World Cup squad.

In December, he underwent a medical ahead of a move to Atletico, before Racing Club criticised the Rojiblancos for not informing them, and Martinez went on to signed a new contract.

Italian clubs especially Inter Milan have a good record of getting the best Argentine players and Martinez, with his talent, could add a lot to the team for many years to come.
