A Swansea free-kick curls out of play for a goal kick and that's the end of the first half.

No goals yet.

We're in to three added minutes at the end of this first half.

David McGoldrick's strike almost goes in off Cameron Carter-Vickers for an own goal, but fortunately for the Swansea defender, his deflection goes straight at the keeper from two yards out.

Swansea's Bersant Celina has space to run at goal and shoot from just outside the area, but his effort flies high and just wide.

David McGoldrick must score... But he heads wide... He just didn't connect with it properly.

It was a peach of a cross to the far post from Mark Duffy, right on to the head of in-form striker McGoldrick.

A well-judged intervention from Jack O'Connell stops Connor Roberts getting through on goal for Swansea, after good football from Wayne Routledge.

The Swans are enjoying a better spell.

Moments later, the visitors' Oliver Norwood is booked for a late swipe at Roberts.

Swansea create a promising opening - with six men in the box - but Bersant Celina overhits his square ball and the chances goes begging.

Martin O'Neill has been speaking to the media after today's defeat by Bristol City.

The former Republic of Ireland boss said there has been no progress on the Roy Keane deal because there hasn't been time, but they will pick that up next week.

"I wanted to leave it and see what happens next week," he said.

"I thought we could get momentum early on but I didn't get that at all. They settled much better. We gave the ball away too easily and that contributed to a nervy first half.

"They were in control. In the second half we got some momentum going and we had a couple of chances as well."

With half an hour gone, the Blades have arguably edged this, but it remains goalless.

Swansea's Oli McBurnie almost feeds Connor Roberts in front of goal, but Roberts just couldn't quite time his run to perfection.

The early substitution means there are now three former Sheffield United players on the pitch in Swansea City colours.

Cameron Carter-Vickers, who was on loan at Bramall Lane last season, joins fellow ex-Blades Kyle Naughton and Nathan Dyer.

The visitors have the best chance yet to open the scoring, but Billy Sharp is denied from six yards by a super save from Erwin Mulder's feet.

Defender Joe Rodon is injured and has to go off for the hosts.

On comes former Blades loanee Cameron Carter-Vickers to face his former club.

This rather stop-start to the match hasn't been helped by a pitch which looks like it's showing a few signs of wear and tear.

Swansea's co-tenants at the Liberty Stadium, rugby union team Ospreys, played against Cardiff Blues here a fortnight ago but the slowness in the pitch looks more like the natural effects of age.

This turf is over a decade old and is due to be relaid next summer. Perhaps that will give the pitch a new lease of life and help teams to play attractive football.

The game's yet to really spark in to life, as the Blades bid to return to second in the table.

Better play from Swansea - orchestrated by Bersant Celina - wins the hosts a corner, but Sheffield United head it away.

A Blades corner is cleared out as far as George Baldock outside the area, who drills a shot over the bar.

Sheffield United are seeing a lot of the ball at the moment. They're spreading it around confidently.

Bristol City boss Lee Johnson wants to add to his squad in January to keep their promotion push on track and said he definitely wants to bring in another striker.

"It's been a good run with seven wins from 11 and we can beat anyone on our day," he tells BBC Sport.

"Last season we had a fantastic start but we couldn't maintain the energy.

"We need to create competition and the finances give you the ability to make changes and not affect the quality of the team."
