The 26-year-old South Korean has had a busy worldwide schedule as he took part in the 2018 FIFA World Cup and the 18th Asian Games in Indonesia, where he won a gold medal.
"We all love the way we work, the style of play".
Tottenham Hotspur manager Mauricio Pochettino has admitted that he will be making a host of changes for the EFL Cup game against West Ham this evening, but insists that his side will remain competitive.
"The fans are incredible, the chairman, everyone - the whole club's unbelievable".
"It is so important for an offensive player to find the net", said Pochettino.
"We are going to assess all the players and it is less than 48 hours to compete again having had the circumstance of playing on a pitch that is so hard to play on - it was tough and a very competitive game".
"We have a lot of work to do, without a shadow of a doubt, but I couldn't be more proud of what the players have all done to get to where we are".
"I've had lots of plaudits about my team, over the last six years, so it's probably our first real tricky spell, so I'm not going to crying it in", the Clarets chief said.
"The stadium and the training ground are great, but you can have all that and still not improve as a player", he added.
The Kiwi forward - who has struggled for starts this season - came off the bench in the 72nd minute, replacing Czech global Matěj Vydra.
"As a young professional, I have to think about what's best for my career and where I can improve".
