Semenyo is really in the mood. He let rip there from 30 yards out. He's so positive in everything that he does.
Newport 1-0 Leicester
Newport's left winger Antoine Semenyo is getting a lot of praise. He has been lively.
Leicester apply a bit of pressure but Mickey Demetriou, who is playing in a protective mask, is on hand to clear twice.
Marc Albrighton then heads over at a corner.
Newport 1-0 Leicester

It's another of those long throws and every time Newport have one they always seem to find a shot at goal.
The Leicester goalkeeper knows he's got to be better than this. One slip and the Newport players will be pouncing.
Newport 1-0 Leicester
Amond is back up and is going to continue. Newport have another effort and Leicester keeper Danny Ward spills it and is left sprawling on the ground like someone looking for the phone they've just dropped in the dark.
Luckily for Ward the offside flag goes up.

It's like a time out. The players have all gone over to the bench. There's a lot of 'well dones' from Michael Flynn.
Newport 1-0 Leicester
Amond might have injured himself in making that cross. He's down on the turf and it gives Michael Flynn the opportunity to speak to a couple of his players.
Here's the goal that has the League Two team in front...
Newport 1-0 Leicester
Newport come close again.
Padraig Amond does excellently down the left to keep up with the ball and fashion a cross. Goal scorer Jamille Matt meets it but just can't get the ball under control before Danny Ward grasps it with his gloves.

Leicester have been held back in their own box, they can't build anything. It's very difficult to deal with this type of play.
Newport are controlling this nicely. When Leicester do get the ball they've got to pass it and be patient.
Newport 1-0 Leicester
Kelechi Iheanacho has had four fewer touches than his goalkeeper Danny Ward so far.

It's brave and it's bold [from Newport]. It has been absolutely brilliant.
Newport 1-0 Leicester
Leicester clear this one. They all pile in at the back post to try and get on the end of Dolan's delivery but Ward punches clear.
Newport 1-0 Leicester
Corner to Newport.
They're winning every header to the minute...

It can happen when you make wholesale changes and don't see the regulars. It's almost feels like a punishment, that you've been asked to come here and play at lowly Newport.
It's a test for you. If Leicester didn't know before the game that they're in a battle then they certainly know now.
Newport 1-0 Leicester
Hmmmm. Leicester win a free-kick in a good position but Rachid Ghezzal doesn't threaten the target.
Claude Puel is stood with his arms folded on the touchline looking like he could combust with anger.
He's furious with his side.
Newport 1-0 Leicester
Newport County 1-0 Leicester City

BBC Sport Wales at Rodney Parade
Newport County and their fans fully believe they are going to do this. The noise in the main stand at Rodney Parade is deafening!
Newport 1-0 Leicester
This is a serious cup tie. Matty Dolan now pings one from the edge of the box and it is blocked by the legs of Danny Ward.
I played tennis against Dolan in my schooldays. I won but now he's playing in the FA Cup.
I think he wins...

If that's a block that's an unbelievable bit of defending. You're waiting for the net to bulge.
But Okazaki should be putting that away. It's a poor header.
