A good watch but no goals so far in the League Two promotion battle at the Copperjax Community Stadium.

Both sides have had penalty shouts, the first for Bromley after Nicke Kabamba was pushed to ground before there was a collision in the hosts' box that did not get ruled in the visitor's favour.

Cambridge have been particularly threatening on the counter-attack with Shayne Lavery coming closest with a header that whacked the crossbar.

Meanwhile Bromley are yet to have a shot on target but were piling on the pressure as the half drew to a close.

Exactly what you want in a race for promotion - and potentially the title.

It has been really intriguing.

Three big opportunities for Cambridge United.

A really physical battle with Bromley's threat from set-pieces which United have dealt with well so far.

There's four more additional minutes to play in this intriguing first half.

Enough for an opener?

That is where Cambridge United could hurt Bromley, on the counter-attack.

Ben Knight will know that from that one-on-one earlier.

They got away very quickly on the counter there.

Bromley have stepped it up a notch these past few minutes.

The hosts earn a corner, seeing it ping around until finally Cambridge find a chance for a counter.

The fast break was serving them well in the early stages of this match but now Bromley's defenders have adjusted as Ben Krauhaus muscles out Ben Knight to win a free-kick and stop the attack.

It is relentless at times from Bromley.

They apply a high press. They force you to move the ball quickly.

Ben Thompson goes for the flashy bicycle kick but that doesn't phase Cambridge defender Kell Watts.

He puts his wellbeing on the line to provide the block, taking a good whack in the process but is soon back on his feet.

Hardened lot, these League Two defenders.

Vale lead at the break.

Early goals from Ryan Croasdale and Ethon Archer put them 2-0 up before James Dornelly pulled one back for Posh.

Big second half coming up, especially for Peterborough.

The referee saw it as a head injury.

If it is, then how can there not have been contact in the penalty area?

Cambridge fans think there's an unnecessary scuffle in the box and when the referee blows his whistle, cheers from the away end ring out.

Not for long though as the finger is pointed the other way in Bromley's favour.

Ben Knight was waiting for the right option.

The ball in from Adam Mayor was absolutely perfect.

Lavery hits the bar. It's another situation for Cambridge United where they should've done a lot better, surely.

Lavery will be kicking himself.

Cambridge's Adam Mayor sends in a pinpoint cross to Shayne Lavery, who jumps high to provide the header.

He gets a good connection but it clatters the bar.

Nicke Kabamba takes an arm to the face to win Bromley another free-kick.

Mitch Pinnock whips it to the middle of the box but it misses everyone and lands at Ben Thompson's feet on the opposite side.

Thompson unwinds an effort but it swirls skywards.

Bromley are winning too many free-kicks.

The more you give away, the more it gives them an opportunity to get those aerial bombs into the box.

Port Vale are living dangerously.

The ball took a deflection and that wrong-footed Port Vale keeper Joe Gauci.

Eli Campbell had to bail him out. It looked like it might creep in.

Bromley's first go at goal isn't half bad.

The hosts get a free-kick and it's delivered by Mitch Pinnock right into the middle for Omar Sowunmi to show his aerial prowess.

He rises high, thumping his header into the ground but rather than bouncing into the net, it's arcing over the bar.

The challenge didn't come, he saw the whites of the keepers eyes and thought he'd have a go at goal.

Sullay Kaikai to his left may have been the better option.

Peterborough have halved the deficit before half-time in this League One encounter.

James Dornelly slotted in from Matthew Garbett's corner.

Still plenty of work to do from Posh against their relegation-bound opponents though.

Cambridge are looking much sharper on the attack.

Ben Knight is the latest U's player to weave into space, rustling up a shot but it's eased into Bromley keeper Grant Smith's gloves.

The hosts are yet to have an effort at goal.

Bromley's Marcus Ifill is walking rather gingerly down the pitch.

Boss Andy Woodman will be keeping an eye on that from the stands, where he's serving his suspension following his yellow card at Stadium MK on Saturday.
