Wolfsburg have remained in contact with Tottenham Hotspur forward Heung-min Son since his arrival in White Hart Lane, according to the Bundesliga side.

Son, a £22m signing from Bayer Leverkusen last season, has been linked with a return to Germany this summer. Schalke, who today (Thursday 25 August) confirmed the loan signing of Nabil Bentaleb from Spurs, have also been credited with interest in the South Korea international, but the club's sporting director Christian Heidel has chosen to distance his side from such speculation.

"Heung Min-Son is an excellent footballer," Heidel said. "We know him from his time at Hamburg and Bayer Leverkusen, but he has nothing to do with us."

Heidel's counterpart at Wolfsburg Klaus Allofs has however confirmed his side's interest in Son. He was quoted as saying by the Evening Standard: "Whether it was his time at Bayer Leverkusen or now at Tottenham, we were always in contact with him."

After a Rio 2016 Olympics campaign with South Korea ended in heartbreak, Son returned to north London last week ahead of his side's Premier League clash with Crystal Palace.

Spurs have made just two additions to their squad this summer in Dutch striker Vincent Janssen and former Southampton midfielder Victor Wanyama. With moves for Espanyol goalkeeper Pau Lopez and Marseille winger Georges-Kévin Nkoudou in limbo, Pochettino remains hopeful of making up to three more additions to his squad before the transfer window closes.

"I am very happy [with Tottenham's transfer activity this summer]. I know this is difficult in this crazy business that today is football," Pochettino told a press conference ahead of Tottenham's weekend clash with Crystal Palace.

"We try [to bring more players in]. We hope to sign one, two or three players – or maybe no-one. It depends on many things that will happen. We will try to find some players to sign."
