The People says Forlan has fallen out with Atletico Madrid boss Quique Sanchez Flores â€“ opening the door for a sensational return to England in the summer.
Spurs have been interested in signing Uruguayâ€™s World Cup star for the past 18 months and will head the queue, but there is also surprise interest from his old club Manchester United, where Forlan, 31, was a Â£7million flop.
The poor relationship with manager Flores means Atletico are ready to cash in on him and will entertain offers of around Â£9m.
Spurs boss Harry Redknapp is looking into all sorts of forward options and has been alerted to Forlanâ€™s availability.
The Uruguayan was linked strongly with a move to White Hart Lane in the January transfer window.
