Manchester United and Chelsea have emerged as rivals for the signature of South Korean starlet Son Heung-Min, according to reports.
The 20-year-old has been a big hit in the Bundesliga since breaking into Hamburger SV's side in 2010, winning 12 caps for his country.
Son has scored nine goals in 19 Bundesliga appearances this season, and The Mirror quotes his value at around £10m.
He joined the youth setup at the Imtech Arena from FC Seoul Under-18s in 2008, when he was just 16-years-old.
