Moussa Dembele is set to be unveiled as a Tottenham player as further doubt was cast on the future of Rafael van der Vaart.

"Mr Levy, the chairman of Tottenham Hotspur FC, personally flew to Donetsk to negotiate over Willian," Palkin told his club's official website, www.shakhtar.com.
"But his latest offer was 15 million euros, which we of course did not accept.
