Tottenham have agreed a deal with West Ham to sign Mohammed Kudus.
The fee for the 24-year-old forward is understood to be around £55m.
Kudus is set to begin his medical with Spurs on Thursday ahead of signing a six-year contract.
If it goes through, this will be the first transfer between the two rivals since Scott Parker joined Spurs from West Ham in 2011.
Spurs remain interested in Brentford's Yoane Wissa after the expected arrival of Kudus.
Chelsea and Newcastle also showed interest in Kudus earlier in the window.
