The 25-year-old has started the new season with Swansea in fine form as the Welsh club currently sit joint top of the Premier League table with three wins from three.
They will face their biggest test of the season so far this weekend however, as they prepare to take on Chelsea at Stamford Bridge - the only other side with a 100 per cent record.
But Ki - who scored the Swans first goal of the new season - has reason to be optimistic ahead of the clash with the Blues as the South Korean midfielder has beaten Chelsea in each of the past two seasons.
Both wins came in League Cup ties, firstly in 2012 when Swansea sealed a 2-0 victory at Stamford Bridge in the first-leg of their semi-final before going on to win the competition against Bradford at Wembley.
Then last year, Ki enjoyed success against Chelsea while on loan at Sunderland as the Black Cats beat the Blues 2-1 in extra-time in the quarter-finals of the competition, with his late strike enough to knock Jose Mourinho's side out.
He has returned to Swansea this season and is thriving in Garry Monk's midfield alongside Jonjo Shelvey, and the Swans will have the opportunity to prove their credentials when they travel to Stamford Bridge on Saturday afternoon.
"We respect Chelsea and honestly, when you look at the players they have, they are better than us."
"But there is always a possibility when you play against a big team. We can win but we have to be better than in our first three games," he said.
Swansea have scored six goals and conceded just one so far this season, and if they can continue to improve they will have a good chance of leaving West London with a share of the points this weekend.
