The teen made his Premier League debut towards the end of last season.
"Collectively, from the more regular starters to those coming on, everyone has been so supportive and has wanted to improve. I'm so appreciative of that because it has helped bring everyone together," said Son in a club interview.
"Sometimes, when we've been in a tough moment, this group has shown that everybody is ready to play for this team and I'm really pleased to see that as captain.
"I really appreciate everyone that's come into the squad, even young players like Mikey Moore who has been training with the group and working really hard, it’s great to see these kinds of things. Generally, across the whole season, it's been very positive, and we've been making steps forward. Obviously, there is still room for improvement, but the overall positive energy suggests it's been a great season."
