Wayne Routledge has been directly involved in three of the last four goals scored between Swansea City and Cardiff City, netting once and assisting twice for the Swans.

Routledge stays cool down the Swansea left, winning a throw for his team.

The oldest player in the Swansea squad has been a calming presence so far.

Neil Warnock is extremely agitated and it is no surprise, his side have been poor.

The Bluebirds lack urgency and conviction and to top off their disdain for the way things are going, they have conceded a headed goal from a set piece.

This game has not followed the script.

Another towering set-piece comes into the Swansea box, with Etheridge launching the ball from his own half.

Swansea are scrambling for a moment but eventually get the ball clear.

Nathaniel Mendez-Laing has been Cardiff's biggest threat so far.

The winger's pace is causing problems down the Swans' right, but the hosts have coped - just about - thus far.

Swansea threaten again as Routledge flicks the ball to Ayew but his shot is well blocked by a sliding Morrison.

From the resulting corner, Ayew heads over.

So it is first blood to Swansea and the volume has gone up a couple of notches at the Liberty.

In truth there has been nothing between the sides, but it is advantage Cooper's men for now.

Swansea strike first and it is a goal on full league debut for Ben Wilmot.

The Swans work a short-corner routine and the central defender gets in front of his man to head Routledge's left-wing cross beyond Etheridge.

Swansea's best passing move so far has Cardiff scrambling for a moment or too.

Home skipper Matt Grimes eventually tries his luck from distance but his effort whistles over the bar.

Derby games are typically frenetic in the early stages and this is definitely a typical start.

Bersant Celina tries his luck from halfway after Cardiff keeper Neil Etheridge came out of his area to clear.

Etheridge then attempts a diving header to block the effort - which was going wide anyway - and the ball goes behind for a corner which comes to nothing.

So far this game is 100 mph and frenetic as they come, but we have not seen too many moments of quality.

The current answer to the question 'which side looks more like a promotion contender?' is currently 'neither'.

Now Peltier is penalised for a foul on Routledge.

There are cheers from the Swansea crowd who feel not much has gone their way early on.

Swansea look to have a decent opportunity to counter as Wayne Routledge gets the better of Lee Peltier, but the referee eventually decides that the Cardiff defender has been fouled.

Swans boss Steve Cooper is not impressed with the decision.

Another set-piece causes some alarm for Swansea, with Nathaniel Mendez-Laing volleying over.

Then Andre Ayew races into the Cardiff box and his dangerous cross is cleared by Lee Peltier.
