Chelsea rescued a late point against Brendan Rodgers\' men courtesy of an own-goal from Neil Taylor in the 93rd minute.Villas-Boas concedes that a draw may have been a fair result but will reflect on what could have been.\"I think there were two different halves in the game,\" he told reporters.\"In the first half, Swansea had most of the chances and it was completely different in the second where we had all the chances.\"I think that if the first goal had come earlier, we would have found a second, because we had the motivation, the impetus and the control of the game.\"We left it very, very late. We persisted a lot to find it, [the goal] but it came late and didn\'t give us enough time to score the second.\"The Portguese boss admitted that he was slightly disappointed with his side\'s first-half performance and felt that they could have applied more pressure to the slick-passing Swans.The 34-year-old said: \"To play against Swansea, you almost have to adapt to a different style and press them hard and make them commit mistakes.\"We didn\'t do that in the first half, we did it in the second half with much more efficiency.\"Normally, Swansea are a team that are prepared to escape your pressure and they are very, very well organised.\"I feel if the first half was like the second, then we would have got another three points.\"The only slight blotch on the evening\'s work for the Blues was the dismissal of Ashley Cole, with the 31-year-old full-back sent off for a second yellow after a challenge on Nathan Dyer.And, whilst Villas-Boas refused to condemn his player, he seemed pessimistic about appealing the red card.\"Well, it is a difficult challenge,\" he said. I think Ashley goes all in on the challenge because he thinks he can get to the ball.\"Dyer just anticipates on the challenge and, I think, Ashley in the end touched him.\"We will have to see the incident again to see if there is any chance of rescinding the card.\"
