Swansea win a free-kick deep in their own half for a foul by Rickie Lambert. That might be it for the hosts...

Another second-sapping change for Swansea as Jonjo Shelvey arrives to replace the excellent Leon Britton.

Wayne Routledge takes his time heading off the pitch to be replaced by Modou Barrow.

There will be just two minutes of added time.

Swansea fans burst into cheers as Leon Britton gets across to tackle Saido Berahino as the West Brom striker threatens to break clear.

The pace of substitutes Berahino and McManaman has got a few nerves creaking in the Swans' defence.

Hello. Trouble here.

Callum McManaman goes down in the box under a challenge from Leon Britton.

He appeals in vain for a penalty and then reacts furiously to something said by Swans' defender Angel Rangel.

A shoving match ensues and referee Roger East dishes out yellow cards to McManaman and Rangel to cool things down.

Callum McManaman replaces Claudio Yacob as we tick into the final 10 minutes.

West Brom's players are showing a bit more urgency, but are still struggling to pick apart Swansea's defence.

West Brom's momentum has slowed as the game breaks up a bit.

Tony Pulis has ordered Callum McManaman to swap a bib for a shirt on the bench.

Swansea are threatening on the break as West Brom press forward in search of a way back in.

The Baggies are caught short-staffed at the back by a swift counter and Ki Sung-yeung comes close to playing in Neil Taylor as he feints to shoot and stabs a pass towards the full-back instead.

Suddenly this is getting very tetchy.

Claudio Yacob leaves his studs in on Wayne Routledge as he challenges the prone Swansea man for the ball. It is a naughty one and all his protestations of innocence cannot convince Roger East.

The ref issues a deserved yellow.

West Brom have made a double change - and it is a punchy one.

Off go Craig Gardner and Jonas Olsson, on come Saido Berahino and Stephane Sessegnon. This is chips-on-the-table time from Tony Pulis.

Saido Berahino is stripped and ready on the West Brom bench...

Rickie Lambert is a growing force in this game.

Picked out by Chris Brunt's cross, the Baggies' striker plants his header too close to Lukasz Fabianski in the Swansea goal.

West Brom have come out with a far more attacking mindset after half-time.

Rickie Lambert has been pretty anonymous so far today, but that was more like it in the classic targetman role he has been asked to play.

His knock-down is volleyed goalwards by James Morrison, but the Scotland international failed to really get hold of his shot and Lukasz Fabianski gratefully gobbled it up.

We are go on the second half at the Liberty Stadium.

A change for Swansea and it is midfield anchorman Jack Cork who is fresh off the bench, replacing Jefferson Montero.

West Brom striker Saido Berahino is warming up on the Liberty Stadium pitch at half-time.

As are the rest of the visitors' substitutes. Is Tony Pulis planning a change?

Swansea's last league win was a full two months ago - when they beat Aston Villa 2-1 away on 24 October.

Before that you have to go back to 30 August for their last three points.

The home fans won't mind how the next one arrives.

Forty-five minutes to go.

It has not been a classic. There have been just two shots on target - both from Swansea players - all half.

The hosts are also shading it in terms of possession and territory.

“Albion have got to sharpen things up for me, they’ve got to be a little bit sharper, a little bit quicker, especially around the box. They’re not really creating a lot."
