The 21-year-old has been on English radars for some time as talks over a new contract in Portugal continue to stall.
Atsu has fallen out of favour under Vitor Pereira in recent months, after refusing to commit his future to Porto.
He now looks set to depart Estadio do Dragao with Spurs boss Andre Villas-Boas believed to be monitoring the Ghana international's situation, as he considers a bid to bring him to White Hart Lane this summer.
Porto are ready to sit down and discuss the offer on the table for Atsu, with the African forward understood to be keen on an opportunity to test himself in England.
Everton are also reportedly keen on the player, but with David Moyes now set to leave Goodison Park and take over at Manchester United next season, it's unclear whether their interest remains.
