Tottenham are believed to be close to signing Bayer Leverkusen's Son Heung-min, with the Bundesliga club's chairman Michael Schade confirming discussions are ongoing.

Sky Sports is reporting Spurs are eager to finalise a deal for the 23-year-old South Korean international who is understood to be set for a medical in North London on Friday.

Schade revealed on Thursday that negotiations are continuing, but a deal is yet to be finalised.

"We are in discussions but there hasn't been any final negotiation," Schade said.

"The next days will show, but we will only let Son Heung-min go when we are satisfied with the terms."
