A bit of a "to do" involving several players from each side ends with cautions for George Evans for a cynical foul and for Duane Holmes, who tried to commit a cynical foul.

We are into three minutes of injury time at the end of the first half.

Some momentary confusion is caused by a ball whipped in at the near post and there's a half-hearted call for a penalty for handball and/or some over enthusiastic defending before Leeds keeper Bailey Peacock-Farrell drops on the ball.

Derby keep the ball at the Leeds end and have a corner...

Another sight of goal for Derby. A cute reverse pass by Tom Lawrence plays in Mason Mount but his goalbound shot is brilliantly blocked by Luke Ayling.

Still only three shot on target for Leeds.

Midfielder Adam Forshaw unleashes a spectacular long-range effort that flies wide. He really caught hold of that.

For all their domination - which is continuing. It's only three shots on target for Leeds. Derby can point to that. And while it's just 1-0...

Nearly 75% possession by Leeds. Sometimes stats can been a little misleading.

On this occasion they are spot on. It's all Leeds.

Derby have enough quality to regroup though. And thanks to spygate, Frank Lampard's half-time teamtalk will be simple in terms of motivating, even if the tactical side of things is not so straightforward.

At least Marcelo Bielsa looks happy, doesn't he? I suppose you can decide for yourselves what Frank Lampard's thinking...

At last. An attempt on goal by Derby.

It's miles off target from Tom Lawrence but at least it's an attempt on goal. Their first. After 34 mins.

More good work by Leeds on the left and the excellent Ezgjan Alioski fizzes in a first-time cross which goes all the way across goal.

Plenty of ooohs and ahhhs from the home fans. An inviting centre if ever there was one.

Derby boss Frank Lampard has his arms folded on the touchline. He is not happy. Not happy with the spying drama and not happy with how this match is panning out.

The visitors are not getting a sniff.

Post-match interviews could be lively.

More probing from Leeds United's Jack Harrison wins a header at the far post but it loops up in the air and Rams keeper Scott Carson claims with no trouble.

Leeds were magnificent when they two sides met in August, running out 4-1 winners. They way this is going it could be a similar margin of victory again.

Derby are very frustrated.

Craig Bryson steams into a challenge. He's barely seen the ball so far.

Dean Plumley: The Falcao and The Snowman

Bodgeman: Cascarino Royale

Bruce MacRae: Drogba No

James Morrison: Zander Diamonds are forever

It's relentless stuff from Leeds and they are having plenty of joy down the Derby right.

Andre Wisdom has already been booked too remember.

But the latest chances comes on the Leeds right. Delightful ball-juggling allows Jack Clarke to cut inside but he drags his shot wide of the near post. That would have been some goal.

After a relatively even first five minutes following the penalty claim, it's been all Leeds. You had the feeling the goal was coming despite the massed derby defence.

Derby are not risking going too gung-ho. They are keeping a decent shape but Leeds are still finding enough room to ask plenty of questions.

Another corner for the home side.

After the feisty comments from both coaches during their pre-match interviews, there was a civil handshake between Marcelo Bielsa and Frank Lampard at kick-off.

Leeds thought they had been awarded penalty after just 30 seconds when referee Andy Davies pointed to the spot... but the assistant had his flag up for offside.

As spies say... "False Flag"...
