Tottenham is interested in West Ham star Mohammed Kudus, in what the first transfer between the two clubs in 14 years would be if a deal was agreed.
Kudus has a £ 85 million clause for Premier League clubs, active for the first 10 days of July.
The Ghanaian attacker is one of the most sellable assets in West Ham, and the London Club has accepted that they are in a position where they have to sell before they can buy.
Tottenham, under new boss Thomas Frank, has made him a primary target this summer, as reported by De Telegraaf.
The North -London side would be optimistic for closing a deal under the release clause of Kudus.
If the deal goes to continue, Tottenham will have to lift their unofficial transfer embargo with West Ham.
The relocation of Scott Parker in 2011 remains the last transfer between Tottenham and West Ham.
Daniel Levy blocked Emmanuel Adebayor to go in the opposite direction four years later and the two clubs have not done any business in 14 years.
Kudus is supposed to be interested in the switch to Tottenham, who would like to strengthen their attack for their return to the Champions League.
Chelsea is also interested in the winger, but they have already agreed deals to sign Borussia Dortmund's Jamie Gittins for £ 55 million and Joao Pedro from Brighton for £ 60 million.
Kudus arrived two summers ago in West Ham from Ajax for nearly £ 40 million and made an immediate impact, which he had yielded 14 goals in all competitions in his debut campaign
He was a bright spot in the midst of a difficult season in the London Stadium, in which he registered five goals and another four assists during his 35 performances in all competitions.
