Tim Sherwood is keen to make the 21-year-old Senegalese winger one of his big money summer signings, however Chelsea, Manchester City and Newcastle have also been linked.
Sherwood has sent scout Ian Broomfield to watch the Red Bull Salzburg star in action twice, and is reportedly ready to launch a bid in the region of £10million for his services.
Salzburg are willing to sell at the right price, but are hoping to start a bidding war following the news that Chelsea, City and Newcastle also have their sights on the left winger.
However Tottenham and Sherwood – who hopes to get the green light to go ahead with the deal from chairman Daniel Levy – are confident that they lead the hunt for his signature.
Mane’s advisors believe he would have more of a chance of starting regularly at White Hart Lane in the Premier League and European competition, rather than at City and Chelsea where he would be considered nothing more than a squad player.
