Not having Lokonga tonight could affect them [Luton]. That's where they are at their strongest and they are blessed to have them [Lokonga and Barkley] because they are such good footballers.

They have so much pace in the team too but losing Lokonga in the middle is where they may struggle. Those two haven't been overrun too much this season.

Enes Unal has another opportunity for Bournemouth, this time with a free-kick but he sends it comfortably over the bar.

Since Luton last played, the gap between themselves and safety has increased to four points after Everton's penalty for breaching Premier League financial rules was reduced from 10 points to six after an appeal.

"Our task hasn’t changed so I don’t see us having to pick anyone up at all," says Hatters boss Rob Edwards, whose side host fourth-placed Aston Villa on Saturday.

"It makes no real difference, we were in the bottom three before and we still are. We're just four points behind Nottingham Forest with a game in hand. We're in the mix. It's not changed our task."

Four brilliant years. Great football club with wonderful people. Some are still here.

For little old Blackburn to come and take on the might of Manchester United and Liverpool and Arsenal and beat them to the Premier League title was really special.

Here come Bournemouth now as Jannik Vestergaard defends really well to prevent Enes Unal hooking in from six yards out.

Leicester continue to do all the attacking as Arjan Raikhy finds himself in a bit of space just outside the box but he panics a bit as he is quickly closed down and sends his shot well over.

I think they will go into it quite positive.

John [Eustace] wants to make sure they are really competitive. It is a cup tie and a chance to get into the last eight.

He will be looking at it as a little bit of a free hit and a chance to see the things he has seen as a team and implement it against a very strong Newcastle team.

Very bright start by Leicester, who are immediately on the front foot and have won a couple of corners before Yunus Akgun had an effort saved.

Kick-off for this game has been delayed by 15 minutes until 20:00 GMT as they look to give supporters more time to get into the ground.

I scored in an FA Cup tie for Blackburn against Newcastle a few years ago - it was a wonderful finish, but we ended up losing in a replay, and I can see the Magpies getting through this time too.

Blackburn drew at the weekend in the 'Chris Sutton derby' against my first club, Norwich, but they are yet to win in four games under new manager John Eustace, and I don't see him getting a first victory here.

Newcastle boss Eddie Howe really needs the FA Cup now, to recover a bit of faith with the fans after some disappointing results, including their heavy defeat by Arsenal on Saturday.

Howe's side should win, because they have got the superior players and I actually feel as if they will run away with this one a little bit.

Prediction: 1-3

You look at their league form and the way things have gone. A Champions League place is out of the question.

Then you are looking at what would class as success for them this season. They are looking at those European places and to end that long wait for a cup would constitute success for them.

Blackburn only missed out on the Championship play-offs on goal difference last season but this campaign has proved a tough one.

Manager Jon Dahl Tomasson resigned in February, frustrated at the club's transfer policy and a shrinking budget with former Birmingham boss John Eustace taking over.

However, from his four games in charge he is yet to win with three draws and a loss to leave Rovers 16th, but only four points above the relegation zone. But Eustace feels his side, the lowest ranked team left in the competition, can perform without any pressure and enjoy the experience.

"This game allows us to play with a bit more freedom, to really take the shackles off," he said. "We're playing against one of the top teams in the Premier League and it's going to be a great occasion. The most important thing is to enjoy the night, there's no pressure on the group."

One positive from this season for Blackburn has been the form of striker Sammie Szmodics. He has got 18 goals in the league to top the Championship goalscoring charts with another five FA Cup goals - a hat-trick in the 5-2 win against Cambridge in round three and a double in the 4-1 victory against Wrexham in the fourth round.

Can he help Blackburn cause a shock tonight?

There are no replays tonight so it's straight to penalties if the scores are level after extra-time. It is 10 years since keeper Tim Krul was sent on in the 120th minute by Netherlands boss Louis van Gaal just for a penalty shootout at the 2014 World Cup.

Krul saved two spot-kicks as his side advanced 4-3 on penalties against Costa Rica.

Will Krul, who turns 36 in April, be Luton's hero against holders Manchester City?

He has been second-choice to Thomas Kaminski in the Premier League this season but has been used in the cup games.

They have got 7,000 Newcastle fans who are going to have the whole of the Darwen End and they will have come here in expectation that they would field a strong time.

It is always good to see strong teams named for the FA Cup and they are.
