Tottenham have received a boost with the news that Heung-Min Son will take part in full training.

The South Korean star is already back from the Asian Cup, while he could feature against Watford in midweek.

Son missed only three games for Spurs, as his country were knocked out in the quarter finals of the competition.

And Son admitted he did not show his best form with Korea at the tournament.

"I wasn't fully prepared," revealed Son to reporters after his country's exit from the competition.

"I felt physically empty. I feel so sorry to have let down my team-mates, coaches and the fans.

"I would rather not speak about it really but I haven't felt right physically. I was losing sleep – I should have looked after my condition better."
