Tottenham are scouting Red Bull Salzburg forward Hee-chan Hwang, a team-mate of Heung-min Son with South Korea.

Hwang has been prominent in Salzburg’s run to the Europa League semi-finals this season, scoring in their quarter-final victory over Lazio that set up the last-four tie with Marseille.

Hwang and Son have struck up a friendship in the national team and Standard Sport understands Hwang, 22, would be interested in the idea of following his international colleague to north London. Son joined from Bayer Leverkusen for about £22m in 2015 and has proved an excellent signing, scoring 30 goals in 96 Premier League games.

Liverpool are also thought to be following Hwang’s progress, as are clubs in Germany and Spain. After three years in Austrian football, scouts believe he is now ready to move to one of Europe’s major leagues.

​Hwang signed an improved deal with Salzburg last year which expires in 2021, but it is thought he would be available for a little more than £13million, and his salary requirements would not be a problem for major European clubs.

Tottenham have rarely hit the mark when signing centre-forwards in recent seasons. Fernando Llorente, bought from Swansea for close to £14m last summer to provide back-up for Harry Kane, has managed only one goal in the Premier League and is likely to leave in the summer.

Roberto Soldado and Vincent Janssen also struggled to make an impact at Tottenham, with manager Mauricio Pochettino admitting it is difficult to persuade top-level forwards to join Spurs as they fear Kane’s presence will limit their time on the pitch.

Tottenham have a busy summer in prospect, with Toby Alderweireld, Danny Rose and Mousa Dembele likely to leave the club, meaning replacements must be found in defence and midfield.
