The Manchester United team and entourage have just arrived into Newport.
Thousands of home fans are in the streets to welcome them.
United are one of only two teams the League Two team have never faced from the top four divisions - Liverpool being the other.
Tickets for this game at Rodney Parade sold out in just little over half an hour on Monday.
There will be a capacity 9,500 packed in with 1,400 from United.
Erik ten Hag has said he’ll be taking a strong team for today’s fixture and is taking no chances.
But he WON’T have Marcus Rashford - more on that shortly...
The United boss said: “We’ll have a strong side.
“We have still some injuries like Victor Lindelof and Tyrell Malacia.
“Marcus Rashford was ill, Jonny Evans was ill so we have to see how they recover.
“But for the rest, we have players returning like Lisandro Martinez, like Luke Shaw, like Harry Maguire, like Casemiro which is a good thing.”
Hello and welcome to today’s FA Cup fourth round coverage as League Two Newport aim to take the ultimate scalp against Manchester United.
County sit 16th in the fourth tier and are – of course – long odds to topple 12-time winners United.
But some might say it’s as good a time as any to take on Erik ten Hag’s men.
Nevertheless, there's a major gulf between the two sides in all aspects.
It will be a good test for County - but one they'll certainly relish.
Will United? That's the question...
A place in the fifth round is up for grabs and we’ll have all the action here!
