The crowd respond as the hosts look to put Chelsea back under pressure.

Lewis O'Brien does brilliantly to win the ball on the left and tees up George Thomason, who sends a low ball across the six yard box which is sent out for a corner.

The Wrexham belief continues to grow.

Sam Smith has been superb. He has given everything to the cause for his team tonight. He has been horrible to play against. He has put a right shift in.

A double change now for Chelsea, as Marc Cucurella and Dario Essugo replace Romeo Lavia and Jorrel Hato.

Phil Parkinson responds with a double change of his own. Goalscorer Sam Smith is replaced by Kieffer Moore, while Josh Windass comes in for Oliver Rathbone.

Wrexham are on top, they are not just having moments. This is a spell of pressure they've got Chelsea under here.

Wrexham appeal for a handball as the ball pinballs around inside the Chelsea penalty area.

The Blues survive - but they are far from convincing at the back right now. A brief VAR check is cleared.

Dobson's delivery causing problems there just as he proved a nuisance for Nottingham Forest in the third round where he managed two assists.

If you're wondering why he's wearing a cast, the midfielder underwent a minor operation in midweek after breaking a bone in his wrist in last week's win over Charlton.

Chelsea are wobbling! The Blues struggle to clear a free-kick, and then almost shoot themselves in the foot when Robert Sanchez plays a short ball to Romeo Lavia.

Wrexham can't punish the Premier League side, but they will keep the pressure on with a corner.

A first Chelsea change is on the way.

Alejandro Garnacho receives the ball to the left of goal but drags a low shot well wide of the far post.

Another Chelsea moment greeted by mocking cheers by the Wrexham fans.

The confidence levels are growing in the stands. There was optimism from the fans around us before a ball was kicked, maybe just based on the fact they've been shown anything is possible over the past five years.

But as this game has gone on, they can see their side are more than holding their own in this game.

Every challenge is being cheered, especially with Wrexham looking like their pressing slightly higher at the start of this second half.

And yes, I was being generous with the "really poor" take on Romeo Lavia's cross there. Just about sums up Chelsea so far this evening.

Really poor from Romeo Lavia, who lifts a cross out for a goal kick as Chelsea attempt to create a first chance of the second half.

Liam Rosenior stares into the distance. He'll be making changes sooner rather than later based on the first five minutes since the break.

It's the same thing again, there is no hesitation from Wrexham.

Ryan Longman whips a cross towards the Chelsea box and wins a corner for his side, sparking the home crowd back into life for the second half.

Max Cleworth then heads over as the ball is recycled. A positive start by the hosts!

I would expect Chelsea to change and come out with a different attitude and a different energy.

No personnel changes for Chelsea at the break, but Liam Rosenior will certainly hope to see big changes in how his players approach this half.

Wrexham are also restarting with the same XI.
