Former England striker on BBC One

On Leicester midfielder N'Golo Kante:

"£5.5m - he has been a revelation. The guys staying in the Leicester team hotel told me very rarely have they seen a guy with such an engine on him. It goes to show, if you look hard, the finds are out there."

Chris Sutton
Former Chelsea & Norwich striker

"A lot of clubs have devalued the FA Cup. If teams aren't going to bother taking the competition seriously they should let fans know and tell them not to bother buying tickets.

"You can't tell me Liverpool needed to make as many changes as they did. Swansea made 10 changes and got what they deserved.

"We shouldn't buy into it when a manager says 'x needs a rest.'

"No they don't."

Alan Shearer
Former England striker on BBC One

"When I used to play against Spurs, I thought we'd be alright today. They have been a soft touch. But, under this guy, they a different side. They have a solid base."

Tottenham manager Mauricio Pochettino on BBC One: "Football is about collectives. There is no reason we can't repeat the performance against Everton. The season is very tough, always the squad is important and we have a strong one.

"The selection is not important, how we play is the most important. We are confident we can do very well."

Emile Heskey
Former Leicester and England striker on BBC One

"Leicester are doing fantastic. Who would have thought they would be where they are in the league?

"As a player when you are riding on momentum, you don't want to be out of the team. But the manager is thinking give the fringe players a chance and it is their time to take it.

"Demarai Gray is fantastic. You have to keep your eye on him, he can create, is quick, can score."

Leicester manager Claudio Ranieri on BBC One, talking about why he has made eight changes: "We play three matches in six days, not possible for us. I want to build a very good team and it is important to understand who are the players who can continue with us.

"They have the chance to show me tonight. To get to Wembley would be fantastic."

Scunthorpe's Neal Bishop pokes a shot just wide and there is the whistle. Professional rather than spectacular but Chelsea are through. 

Peter Crouch
Stoke striker on BBC One

"Tottenham have a serious chance of making the top four and going far in this competition. The manager has got them looking refreshed."

Republic of Ireland manager Martin O'Neill on BBC One: "It's been a phenomenal year for Leicester. They have been sensational, absolutely sensational. You thought they would lose momentum but quite the opposite, they have gone from strength to strength."

Alan Shearer
Former England striker on BBC One

"I used to hate being left out of a side, I wanted to play every game. I can understand resting players for teams who have been in Europe but for the likes of Leicester, out of the League Cup, 47 games if successful is the most they will play.

"I don't think that is too much to ask for."

Alan Shearer's suit... he looks like he's spent the morning at a christening.

One of the best pundits, mind. He was quick to rib Peter Crouch over a bad miss yesterday.

What a hit! Scunthorpe full-back Jordan Clarke smashes in a shot on the run, Carlos Alberto esque, huge bend and power on it and Asmir Begovic tips it onto the post!

That would have been one of the FA Cup's great consolations.

Diego Costa gets a huge reception from the Chelsea fans as he is withdrawn with a hint of a limp. It's been a physical, but successful afternoon up top.

He is replaced by Bertrand Traore. 

Republic of Ireland manager Martin O'Neill is flanked by Stoke striker Peter Crouch and ex-Newcastle striker Alan Shearer on BBC One.

Not a bad front two. And O'Neill, many of you will know, is a former Leicester manager.

I remember those days well - Muzzy Izzet, Matt Elliott and Steve Walsh et al.

Scunthorpe have kept going in this second half and Paddy Madden floats an ambitious effort over the top from a good 35 yards out.

Just over 10 minutes to go in what has in all honesty been a bit of a flat game. 

Those of you watching on the little black box might just have invited Gary Lineker into your living room. If your dial is set to BBC One, of course.

We've moved seamlessly from one heavyweight of the small screen (Attenborough) to another (Lineker).

And what a game we've got in prospect: second in the Premier League against fourth in the Premier League.
