Ki Sung-Yueng says it is crucial Swansea build on the point they picked up against Chelsea, when they take on Southampton this weekend.
Even though the Swans were denied all three points as Diego Costa struck at the death to earn the visitors a 2-2 draw, it was still viewed as a point gained rather than two dropped.
Ki played the full 90 minutes following a summer that was disrupted by having to go on military service, and he was encouraged by the performance of the side.
Swansea can take heart from the second-half performance after what has been a tough start to the season, and Ki says they have to take it into the game against the Saints, who have also struggled.
“We deserved a point from the game because we really improved in the second half against Chelsea,” he said. “It was a busy second half, and aside from the goals we also created further chances.
“It’s a very useful point, and we can go into Sunday’s game against Southampton with confidence, although we know it will be a tough game.
“When the boys are on it, we can challenge the best in this league. Everyone has to be at their best, and that is the challenge for us.”
