Here is the goal that separates the side at Aggborough.

It could well be one we see a lot of in years to come if this game stays how it is...

Good handling from Michael Cooper at the near post, gathering Mason Mount's delivery which was arrowed towards Callum Hudson-Odoi.

Any spillage and it could have been the leveller.

Fox: This pitch is like playing on a plate of Walkers Crinkles! Fair play to Kidderminster though, they deserve it and their fans are in great form (I'm a West Ham fan!)

(Other crisps and snacks are available...)

This sums up West Ham so far.

No pressure on him at all and Ben Johnson strokes a pass designed for Mark Noble straight out of play.

West Ham’s players eyes are really on the ball, when they play on the Premier League carpets their heads can be up but today they are having to take a lot more care.

Is it going to be Plymouth's day??? Is it written in the stars??

For the third time in 36 minutes, Chelsea strike the woodwork.

It's Mateo Kovacic again, taking a touch on the edge of the box and fizzing a low drive against the post.

More brave defending from Kidderminster as Caleb Richards dives in to head away as Andriy Yarmolenko attempts to volley at goal.

Bodies on the line.

Thomas Tuchel is not here because he's isolating, but he'll be fuming at home.

The German will be on WhatsApp video call to his side-kick Arno Michels at the break.

"Sort it out!!"

Andy: To be honest, we're awful all over the pitch, but Diop is especially terrible. Looks like he's never played football before. Could Moyes REALLY not find anyone in the transfer window good enough to compete with him? Embarrassing.

Ryan Fredericks clears the stand behind the goal and sends the ball off into the car park. Tick that off your FA Cup bingo card.

Much better from Romelu Lukaku, spinning on the edge of the area and thumping a low drive which Michael Cooper gets down to push away.

Now we're talking.

Matt Preston follows Said Benrahma, stops him breaking into space and then slams into a fair tackle that sends he ball flying to safety.

What?? Jordan Garrick is from mine and Dawksey's neck of the woods in Liversedge, West Yorkshire.

Apparently he could have played rugby league for Bradford Bulls.

Jack Lovatt: At the rate it’ll be a huge upset if a Premier League club gets through this weekend, great viewing so far!

Half an hour gone, we saw what happened last night when a Premier League side failed to take the opportunities that fell their way.

West Ham really haven't responded to falling behind. These are conditions they are unused to, but the players are good enough to adapt. Takes a bit of heart as well as ability at times like this.

I like Kidderminster's attitude, yes, the ball is bobbling about and the elements are hard but they are getting on with the game and having the better of it.

It's just a brilliant ball to the back post and Callum Hudson-Odoi is first to it.

Can Plymouth sustain this for 90 minutes? That's the big question now.

Chelsea hit the crossbar again!

It's exactly the same spot Mateo Kovacic hit, but this time it's Callum Hudson-Odoi nodding his effort from six yards out against the woodwork.

Should have scored from there really.
