Tottenham star Heung-min Son is facing the prospect of missing the Premier League's return to full training due to a new government plan for people arriving in the UK.
The 27-year-old, who has undertaken two separate fortnights in quarantine, is likely to have to self-isolate for another 14 days with the authorities tightening up measures for those jetting into the country.
Son is currently undertaking his mandatory three-week military service in South Korea during the top flight's suspension due to the coronavirus outbreak.
The Spurs forward was instructed to self-isolate in February after returning from arm surgery in his homeland, before being forced to once again complete another spell in quarantine in Seoul last month.
