Quote MessageCardiff have got nothing to lose, they've got to get the men forward... they have to open up slightly but that might help Swansea.
Swansea 1-0 Cardiff

Quote MessageNobody has played in more south Wales derbies than Nathan Dyer, that was his eighth. He's got three goals in the derbies, he couldn't add to that tally today but he's played his part in giving the Swans the lead.

Warnock is deep in conversation with his staff, presumably discussing another possible substitution.
Cardiff need to change something here.
Sam Surridge for Nathan Dyer
Now Swansea make their first change of the day, with Dyer getting a big ovation as he makes way for Sam Surridge.

Quote MessageI think Cardiff have got to do something about it now, there's no threat from anywhere at the moment, Mendez-Laing not even getting a touch of the ball. Are they just happy to battle like this for 90 minutes or are they going to be a bit positive and get somebody on there?

Another stoppage here as Robert Glatzel and Lee Peltier receive some treatment.
It looks as though Omar Bogle is about to enter the fray.
