TalkSPORT reports how the 26-year-old midfielder has been heavily linked with a move away from Italy, as a number of admirers from the Premier League consider bids for the Colombian's signature.
Former Manchester United manager Sir Alex Ferguson was believed to be keen on bringing Guarin to Old Trafford, but following his retirement it's unclear whether the recently crowned champions are still in the market for his services, following the appointment of David Moyes.
Spurs boss Andre Villas-Boas is now in pole position to sign the £17million-rated star, having worked with the player during their time together at Porto.
The Portuguese tactician will try to use that to his advantage as he bids to convince the South American star to swap Inter Milan for White Hart Lane ahead of the 2013/14 campaign.
However, both Tottenham and Manchester United have been dealt a blow in their respective pursuits of the player, after Guarin hinted last week that he intends to stay in Serie 'A'.
"Guarin? His words were welcomed," said Moratti. "He is one of the most requested players on the market, but he's one of the players who we are counting on the most too."
