The South Korea international has emerged as a forward target for Spurs, who have failed to reach an agreement for Saido Berahino, and a deal looks to be edging nearer
Bayer Leverkusen sporting director Rudi Voller has confirmed that Heung-Min Son had a medical at Tottenham on Wednesday ahead of a potential move, but maintains that no deal has yet been struck.
Spurs have long been pursuing a move for West Brom striker Saido Berahino, but saw a second bid for the 22-year-old rejected on Tuesday.
The club appear to have subsequently turned their attentions to the South Korea international, who scored 17 goals in all competitions last season, but Voller insists that the two clubs are yet to formally agree a transfer.
“There is a request and there are talks. But nothing is done. Son would not have played today anyway, he was sick at the weekend already. At this moment he is our player,” he told Sky.
“I saw many medicals in this business where there was no deal afterwards.
“We will try to reach an agreement, but only under our conditions.”
