One thing Puel has done is introduce James Maddison at half-time. The midfielder comes on for Shinji Okazaki.

It's what you need to do when you're Newport. They've got pedigree, they know what it takes at this stage of the FA Cup and they've started exactly how they needed to start.

I thought they could put Leicester under pressure, their midfield and the big boys at the back, and they've done it.

The Newport chairman is currently on BBC One.

He just said he missed his side's goal because he went to the toilet.

Schoolboy error!

Newport have been magnificent, the effort they've put in and how professional they've been.

They've obviously worked on their set-pieces because they've caused Leicester all sorts of problems.

There's been chances for both teams, it's been a brilliant first 45 minutes.

Elsewhere, Doncaster beat Preston...

QPR beat Leeds...

And Watford beat Woking...

Fulham

Fuham boss Claudio Ranieri to Match of the Day: "The first-half was boring for us, the second-half much better, we scored a goal and had chances to score, but then at the end they deserved to win. They made two goals had another great chance and well done to them.

"I gave a chance to them [the players] to show if I am right or wrong to see if I am right to choose other players, I am right.

"I did not see desire or passion, I wanted to see desire, show me I am wrong, show me! I am not wrong,"

"I am very disappointed, if we played as well as we play in the training session, we win the match. I don't know what happened for these guys."

On the Aleksandar Mitrovic substitution just before the penalty: "I wanted to make the change, Tom Cairney told me he wanted the change. Mitrovic is our man for penalties, but it would have been much better if he had scored early without the penalty.

"I wanted to go far in the FA Cup, but well done to Oldham."

Millwall meanwhile saw off the fellow Championship side Hull City...

As it stands Leicester are the second Premier League team going out to League Two opposition today.

Fulham were knocked out by Oldham earlier.

Here are the highlights...

Paul: If you didn't know anything about football but watched this you wouldn't know which of Newport or Leicester is meant to be the premier league team.

John Dunthorne: These EPL teams deserve what they get. They leave their most influential players out or on the bench, and replace them with non battle hardened squad members not used to playing together.

Rachel T: Underestimate Newport at your peril - best regards, All Spurs Fans.

Without a doubt Newport deserve their lead. Leicester are running out of ideas. They did start to tire a little towards the end of that half though so that is something to keep an eye on. Michael Flynn would have learnt a lot from last season's FA Cup run. They have frustrated Leicester and Claude Puel needs to think about making some changes fairly quickly.

Shinji Okazaki is the first player to receive a yellow card. He gets it for a late tackle.

There is one minute added at the end of the first half.

These Newport players have put so much effort into this first half. I can't believe where they are in the league because they have been really impressive so far.

The corner comes to nothing. Claude Puel applauds his players. They have created chances but have been wasteful.

There are just a couple of minutes left for Newport to see out until half-time. Leicester have a corner...

Martin Keown

Newport are very well set up, the way they're closing. They're trying to let Leicester's central defenders have the ball and hope they give it away.

You can see the confidence from the manager oozing through the players' veins here.

Newport County fans now serenading BBC presenter and well known Leicester City supporter Gary Lineker.

"We ate all your crisps, we ate all your crisps, Gary Lineker, we ate all your crisps."

It's unique, you have to give them that....

Demetriou again! This is an important block, even if he might not have known much about it. It's Shinji Okazaki with the volley from eight yards and it hits Demetriou with goalkeeper Joe Day struggling.
