The 22-year-old insists he will remain at Swansea, despite being linked with a January move away form the club.
“I’m happy here,” said Sinclair.
“I’m under a manager who has confidence in me and I’m playing week in, week out – and there aren’t many players who can say that.
“I’m enjoying being here and learning from the manager.”
Sinclair has 18 months left to run on his current contract with Swansea.
