Barcelona boss Tata Martino is hoping to tie down Toni Sanabria to a long-term deal before Arsenal, Liverpool or Manchester City attempt to intervene contract talks.

The 17-year-old has a €3million release clause in his contract and the Barca boss fears another exciting prospect could be offered a professional contract from a Premier League side, an incentive that Spanish clubs cannot offer until a player reaches 18 years of age.

Catalan newspaper Sport reports that Martino has already held talks with Sanabria in an attempt to keep him at the Camp Nou.

Liverpool used the La Liga ruling to their advantage earlier in the year when they poached Sergi Canos, while Arsenal have somewhat taken liberties snapping up Cesc Fabregas, Fran Merida, Hector Bellerin and Jon Toral all from Barca.

The Paraguay international has trained with the senior team before but continues to play for Barcelona B in the Spanish second division, and may feel he is ready for the step up to play at a higher level.

Barca will have to pull out all the stops as Sanabria can follow in the footsteps as Fabregas, who gained regular first-team action shortly after arriving at the Emirates, while Liverpool boss Brendan Rodgers is renowned for giving youngsters opportunities at Anfield.
