Tottenham striker Heung-min Son has been seen training in a face mask ahead of the World Cup.
The 30-year-old has not played for Spurs since fracturing an eye socket playing against Marseille in the Champions League earlier this month, but last week declared himself fit for the mid-season tournament.
Son swiftly underwent an operation on the damaged area and was subsequently ruled out of Tottenham’s following three games before the break.
Upon announcing his squad for the World Cup on Saturday, South Korea head coach Paulo Bento said of Son’s fitness: “We are in contact with him, with the Tottenham medical department, but about the exact time, the exact day he can train with the team.
“We need to analyse day-by-day his situation. We have time to decide and the most important is he recovers as well as possible, he feels comfortable and then we will take the final decision.”
