Tottenham Hotspur forward Son Heung-min is unaware of any offers to return to Germany, but admits it "is not a good sign" to see his future at White Hart Lane come under scrutiny.

Son, 24, scored 10 goals in 44 appearances during his maiden season in English football. However, the Daily Telegraph claimed, in July, that Mauricio Pochettino was ready to let the player go just 12 months on from his arrival – if they can recoup the £22m they paid Bayer Leverkusen for his services.

Following the forward's return from South Korea's Rio 2016 campaign, speculation over a return to the Bundesliga has mounted. While Schalke chose to distance themselves from reports of a bid for Son, Wolfsburg sporting director Klaus Allofs reiterated the club's long-term admiration for the player.

Son is currently back on international duty with South Korea but could yet return to Europe in the coming days should a move transpire.

"I haven't heard anything about my transfer," he said. "I don't want to think about things happening outside the stadium. I just want to focus on playing football," Son was quoted as saying by South Korean news agency Yonhap News.

He added: "It is not a good sign that transfer rumours are coming out. But I think it is meaningful that those in Germany acknowledge me."

Son was an unused sub in Tottenham's 1-1 draw with Liverpool on Saturday 27 August.

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 earlier this month.

"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."
