At the moment you are just looking at who is capable of unlocking the door.

You kind of almost don't see a goal going - and certainly Wednesday have been incredibly limited in the amount of time they have spent in the opposition half.

Swansea look to run in behind for the first time but Sam Clucas is caught offside. It is a good job too because he was able to make a diving header just five yards out...

All those suggestions on how to settle a tie wouldn't go a miss at the moment. Who fancies a mid-half egg and spoon race?

It's all Swansea at the moment as you can see from the heatmap on the left but despite all their possession, they have still yet to create any real chances.

All-in-all, it's been very flat.

Smart free-kick from Swansea. Ki Sung-Yueng slips it out wide to Tom Carroll and his cross finds Tammy Abraham.

It goes out for a corner and it's another dangerous ball into the box but Wednesday just about get it clear.

It's back with the hosts again now and Wednesday have their backs to the wall.

It opened up a bit for Joao there. He might have had a go at Kyle Bartley. I don't think we've seen one player from either team try to run in behind. Everything's been in front of the opposition.

Sheffield Wednesday's supporters belt out a rendition of God Save the Queen, Swans fans are right back with a version Hen Wlad Fy Nhadau.

The football is not great, the weather is positively Baltic, but at least the fans are in good voice.

Lucas Joao has looked lively so far. He does well to skip through a few challenges in midfield before laying it off to Adam Reach out wide.

Swansea eventually win the ball back but lose it again minutes later. Joao is on the ball again but he gets it all wrong on the edge of the box and passes it to nobody - which then goes out for a goal kick.

Sloppy.

Swansea whip a ball in from that right-hand side again but it's far too close to Kristofer Nordfeldt and Sheffield Wednesday clear.

Sheffield Wednesday have dropped deep. It's more like five at the back, with Joao up top on his own. Fifteen minutes gone now and there's not been one shot at goal.

Remember that man I was referring to earlier without his top on? Well here he is. The man, the legend... the coldest person in the stadium.

There hasn't been a shot at goal yet and we're 14 minutes into the first half...

Conor McNamara has been impressed!

That's better from Fernandez. It's good to see a centre-back trying to play forward. So many in the Premier League just play side to side

Swansea are attacking hard down that right hand side in the opening stages of this match. Do they see weaknesses in Daniel Pudil and George boyd?

Joao then tries an audacious volley in the box but he can't quite make contact with the ball and he ends up looking a litle bit silly...

Lucas Joao whips a ball in from the right but it flies over the heads of everyone. That looked dangerous though...

Sheffield Wednesday have gone with two strikers - Jordan Rhodes and Lucas Joao - but it means Swansea seem to have one man free in midfield at the moment.

Is Jos Luhukay taking a risk here?

Evening from the Liberty Stadium. It's been warmer in South Wales, it's currently a balmy -2, so not a night for extra-time and penalties. There aren't many in either, we're expecting an attendance of around 8,000, but it's a big night for both teams.

Swansea haven't reached the quarter-finals of the FA Cup in 54 years so this a great opportunity for them and Sheffield Wednesday, despite all their injuries, will also believe this could be their night and over 1,200 away tickets have been sold, which is a great effort given the conditions and what must have been a difficult journey down here.

We have commentary on 5 Live now.

First corner of the game falls to Swansea but Kyle Bartley can't make clean contact.
