I say Leeds have got plenty of time but they haven't had an effort on target in the second half. Sutton keeper Ross Worner must have been expecting a tougher afternoon than this. 

Leeds have just over 20 minutes to rescue this tie. Plenty of time. They are readying a third and final change. 

The Cupset Claxon is ringing loud!

Non-League Sutton are ahead against Championship side Leeds through this emphatic Jamie Collins penalty.  

Marco Silvestri comes for a free-kick and juggles it unconvincingly, but Sutton can't capitalise. At the other end Mallik Wilks has gone straight through the middle for Leeds.

It is scary to think about. I don't think anyone can know what Wilks has been through.

You only imagine football gives him a chance to take his mind off things.

Give him credit for even being here.

This is quite a story then.

Mallik Wilks, whose brother was murdered in Leeds on Thursday, is on for his Leeds United debut. 

An incredible turn of events. He is only 18.

Leeds are having nearly all of the ball now, but it's slow and steady possession which is not hurting the massed ranks of Sutton. In fact the hosts look dangerous on the break, Craig Eastmond eats up the yards and Nicky Bailey shoots over.

Sutton 1-0 Leeds

Having said earlier on that I don't see any problem with these artificial pitches, there's one downside.

Sutton midfielder Adam May goes into a 50/50 and ends up with a nasty looking gash/burn on his thigh. Stinger! 

Nine changes for Manchester United from the side that faced Hull City in the EFL Cup semi-final on Thursday.

The only two survivors are defenders Chris Smalling and Marcos Rojo. Among those starting are midfielder Bastian Schweinsteiger and 19-year-old Timothy Fosu-Mensah.

Schweinsteiger's last United start? Against Sheffield United in the FA Cup last January.

Man Utd XI: Romero, Fosu-Mensa, Smalling, Rojo, Shaw, Fellaini, Schweinsteiger, Mkhitaryan, Mata, Martial, Rooney. Subs: Pereira, Blind, Tuanzebe, Herrera, Young, Ibrahimovic, Rashford.

Championship strugglers Wigan are unchanged from the side that beat Brentford 2-1 last weekend. 

Wigan XI: Haugaard, Buxton, Perkins, Warnock, Power, Morsy, Grigg, Connolly, MacDonald, Jacobs, Burn. Subs: Jaaskelainen, James, Kellett, Tunnicliffe, Morgan, Wildschut, Browne.

Sam Pougher: Rightly deserved penalty for Sutton and great penalty taken. Lets hope they can keep the lead

Greg Morter: Get in Sutton United amazing #magicoftheFACup

These remaining 35 minutes will feel like years for Sutton United fans. Leeds send on the rapid Hadi Sacko for Stuart Dallas.

I don't think Jamie Collins will score a more important goal.

It was a very well taken penalty. 

Even if Silvestri had gone the right way, I don't think he would have saved it.

Sutton are the ones who have dominated the game. They deserve to be 1-0 ahead.

Leeds are already readying some substitutes. Needs must.

Sutton have been a little bit flat at the start of the second half. They need to get back to taking the attack to Leeds.

Good play from Leeds winger Billy Whitehouse, who cuts in from the right wing and sees a low shot deflected wide of the far post.

Leeds needed a corner to find a breakthrough against Cambridge in the cup and they have one here - foul.

Sutton have come out a little slower than the first.

Leeds might have had a talking to at half-time from Garry Monk. They seem to have come out with a spring in their step and very much on the front foot.
