A tasty cross from Max Arfsten into the Wrexham box but it can only graze Riley McGree's head.

Surely, a goal has to come in this...

Edvin Austbo is coming on for West Ham, adding pace and trickery, with Manor Solomon making way.

This could have been 3-3.

Cardiff have gone to pieces at the back and a loose header breaks for Jarrod Bowen to take the ball on his chest and race in on goal but Nathan Trott is swiftly off his line to smother at his feet.

Wolves are turning the screw up in the Bristol City end to prompt the away support's encouragement but, again, they do absolutely nothing with their time in the final third.

One of the visiting fans behind the goal looked spellbound as he witnessed Scott Twine's goal in the first half. You can see why. He's not been treated to any kind of spectacle from his own side so far.

Down the other end go Cardiff and Perry Ng tests Mads Hermansen with a low shot which the keeper holds down to his right.

The traffic is one-way here and you feel if West Ham get one....

Manor Solomon spins and sees a shot charged down while Joel Piroe can't quite get on the end of another low cross into the box.

Jarrod Bowen has come to life since half-time and is flitting around a lot more centrally and the Irons are all the better for it.

Joel Piroe then unleashes a thunderous shot from 25 yards out, leaving Nathan Trott flat-footed, but the ball swings away from target and misses the post by maybe six inches.

This place now is a complete different stadium to the one that was so quiet for much of the first half.

Reading come close again.

Ciaron Brown slices an attempted wildly with the ball looping past Simon Eastwood but coming back off the crossbar.

They've been denied by the woodwork twice in quick succession.

First minute on the pitch and Boro substitute Myles Peart-Harris is already being mistreated.

He's fouled by George Dobson, who earns the game's first yellow card.

A triple change for Boro.

Max Arfsten, Riley McGree and Myles Peart-Harris are on.

Kyle Joseph, Luke Ayling and Sebastian Berhalter are withdrawn.

Work for Wolves to do at Ashton Gate.

We are back under way for the second half over in Bristol.

A great backheel from Lewis O'Brien is into Wrexham defender Callum Doyle, who works it towards the box.

He takes too long on the ball though and the space closes in on him.

Boro changes incoming. They've not featured too much in this second half.

Good spell of pressure from the visitors but though he twists and turns at the back post after Cardiff make a hash of clearing a cross, his low ball into the mixer doesn't quite reach Jarrod Bowen in the mixer before Joel Bagan cuts it out.

Rubin Colwill is heading off 10 minutes into the second half for the hosts to be replaced by his younger brother Joel.

Chris Willock is also heading off with Cian Ashford coming on to cause the Hammers defence more problems.

The watching Craig Bellamy will be pleased.
