Jamie Carragher says Cardiff fully deserved their 1-0 victory in the first-ever top-flight south Wales derby.
Steven Caulker broke the deadlock in the 62nd minute when he leapt above Chico Flores to head Craig Bellamy's corner in at the near post.
There had been few chances for either side up to that point in a tense south Wales derby, and the hosts held on to claim a sweet victory over their rivals, with Swansea goalkeeper Michel Vorm being sent off in injury time. Read the full match report here.
"They [Cardiff] have not got the players that Swansea have got on the ball," he told Sky Sports. "We talked about the first 10 or 15 minutes, it was difficult for them. But the tackle from Turner, 20 minutes in, lifted everything after Michu had had a couple of chances and you were worrying for Cardiff a bit.
"Then it became what we expected from a derby game with the atmosphere. The way Cardiff came out in the second half they fully deserved to win."
Carragher added that Bellamy, 34, will relish the victory more than anyone after providing the assist for Caulker.
"As a local lad it will mean that bit extra," he said. "This is probably the biggest fixture for both teams. He got the winning goal last time out and he played a major part again today."
Carragher said that Michel Vorm was rightly sent off when he charged out of his area and knocked down Fraizer Campbell, who was racing on to a long-ball with just the keeper to beat.
"It is a sending off and we talked about the changes Cardiff could make at half-time," Carragher said.
"I think he would have got on the end of it and he would have put it in. Out of the nine goals they [Cardiff] have scored this season seven have come in the second half so they look like a team that, after half-time, come out well.
"We saw that before the goal they totally dominated Swansea in possession, which is something you don't expect from them."
Fellow pundit Dean Saunders said Cardiff were always capable of claiming the victory with a setplay.
"We thought before the game that Swansea would have most of the ball," he said. "I saw Cardiff a lot last season and there were a lot of games like that, where they didn't have a lot of the ball but could score from setplay.
"And I would bet the manager - he probably wouldn't admit it - but he would have said, 'we can beat these on setplays today if we just stay in the game'. That is what happened."
