Erik ten Hag keeps talking about how every single game is so important to him and the club - he knows with the takeover that is happening a good cup run and getting to a final would go a long way towards saying he is the man for the job
If United turn it on it will be difficult but I believe Forest can win tonight.

You can't talk about an FA Cup tie between Nottingham Forest and Manchester United without that famous game in 1990 being mentioned.
Forest were favourites for a third round tie, with many feeling Sir Alex Ferguson would be sacked if the home side won.
That view has been rejected by those who would have made the decision but they were never tested.
Mark Robins' header sealed a 1-0 win for United, who went on to lift the cup and set up Ferguson to become one of the greatest managers ever.
Chelsea 0-1 Leeds

Leeds United went close with Dan James who tried to lob Roberto Sanchez but he didn't get his angle right.
It's bad play from Chelsea, they get robbed inside their box and Mateo Joseph's hits it as hard as he can!
I do not know what Chelsea are playing at!

Bruno Fernandes is very creative and a lot of goals and chances come through him. He can be frustrating at times, he gives the ball away but he is willing to make mistakes to get that final ball or shot right. It's a big game for him.
Chelsea 0-1 Leeds
The away fans are absolutely loving it at Stamford Bridge at the moment. Limbs, as they say.
Leeds haven't lost after taking the lead this season.
Nottingham Forest v Manchester United (19:45 GMT)
Nottingham Forest
Nottingham Forest manager Nuno Espirito Santo on BBC One: "The players have been told to focus on tonight's game and nothing else. We didn't play well against Aston Villa so we have made some changes.
"The idea tonight is to start much better."
Nottingham Forest v Manchester United (19:45 GMT)
Manchester United
Manchester United manager Erik ten Hag on BBC One: "We have players who are not 100% fit but we have to deal with it, we are struggling at the back to have players available.
"We want to win every competition and this is the last trophy we can win this season. In four games we can win a trophy so we have to give everything to win tonight.
"We expect the players to play with passion and desire and resilience."
Mateo Joseph (8 mins)
A first senior goal for Mateo Joseph!
What are Chelsea doing?
They try and play out from a goal kick - after Dan James should have perhaps scored after getting in behind Alfie Gilchrist.
Axel Disasi tries to find Moises Caicedo but he's caught in possession.
The ball falls for Mateo Joseph, who drills home. A superb finish.
Wolves v Brighton (19:45 GMT)
Chelsea 0-0 Leeds
More cheers from the away fans as Raheem Sterling miscues a volleyed cross straight out of play.
It was a lovely dinked ball over to the England winger but his left-footed cross just dribbles out.

The FA Cup is United's last chance to win something this year and the Champions League is going to be difficult to make this season. They haven't won the Cup since 2016 and it's a huge game for them tonight.
Chelsea 0-0 Leeds
It is a pretty scrappy start at Stamford Bridge.
There's cheers from the away fans as Malo Gusto chips a pass straight out of play.
Wolves v Brighton (19:45 GMT)
Brighton chief executive Paul Barber says the club have an "attractive package" for players and staff and want manager Roberto de Zerbi to stay "as long as possible".
Barber told BBC Radio Sussex: It's not rocket science to work out that the better someone does in a job, the more they're going to be linked with other jobs and potentially at bigger clubs that are playing in even higher-level competitions than us.
"But when we're operating in the top six or seven of the Premier League, when we're in the last 16 of the Europa League, when we're still in the FA Cup - we're operating at the highest levels of the game, so we're confident we've got an attractive package here to want to work with and stay with us.
"We've got to shed off this constant thing of 'we're a feeder club for the bigger clubs, whether it is players, coaches or staff'. We're actually doing OK.
"We're still humble, we're still very cognisant of where we've come from and the journey we're still on, but we've also got a lot of good things going here. I'm confident that means a lot of good people want to come here and also stay here."

It was very important for me to win the FA Cup, I loved it while growing up. To win it as captain was a special day for me in 2016.

Benjangles: Amrabat at left back!? For me that’s a very very bad decision .. United have two CBs on the bench and Dalot and Lindelof starting who play full-back. Odd choice
Chelsea 0-0 Leeds
Nervy for the hosts!
Alfie Gilchrist is playing at left-back tonight and his back pass to the returning Robert Sanchez is a little short.
The keeper gets there just in time to clear before a Leeds play is able to charge it down.
