Barcelona are desperately trying to renegotiate a new deal for wonderkid Antonio Sanabria - to stop another teenager defecting to Arsenal.

Arsenal, Manchester City and Juventus are all in for the 17-year-old Paraguayan striker who has a clause in his contract allowing him to leave for £2.5m.

Gunners boss Arsene Wenger has been tracking the teenager after he was highly recommended by his scouts and Arsenal have a long history of poaching kids from Barca.

Arsenal have snapped up Jon Toral, Hector Bellerin, Cesc Fabregas and Fran Merida in the past and Julio Pleguezuelo Selva is the latest one to have made the switch.
