Tottenham Hotspur can call upon Son Heung-Min for the last time this weekend when they face Manchester United before he departs for Asian Cup duty.
The South Korea international will join up with his team-mates in the United Arab Emirates ahead of their final group game against China on January 16.
If the Koreans perform as expected, Tottenham will be without Son until February – and he will be missed.
However, the 26-year-old wants to make sure that he leaves having given Spurs the best chance of staying in Premier League contention.
Tottenham take on a resurgent Manchester United side on Sunday evening as they attempt to keep tabs on leaders Liverpool and Manchester City.
“It’s not easy for me to leave the team at this important time,” Son told Sky Sports.
“I feel very sad and sorry, but I want to win this game and go with confidence to Dubai.”
Son has already interrupted his time with Spurs once this season to represent his country.

However, that earned him and his team-mates exemption from military duty, meaning a potential longer absence from Spurs in the future was avoided.
Son says the best thing for him and Tottenham would be to leave after a winning performance against United.
“To play for your country is always a proud moment, but it’s tough for me having missed one month of the season already,” he added.
“I want to go with three points, with confidence to Dubai.”
Tottenham lie six points behind Liverpool, two behind City and are 10 clear of United, who last won at Spurs in March 2012.
