Matthew Upson
Former England defender on BBC One
It has been a great team effort so far. I think that is the power of Luton Town, they have a great team spirit.
Luton 2-1 Chelsea
Can Luton match the energy from the first half? Won't be easy.
Liverpool 0-0 Norwich
Great hit! Curtis Jones cuts inside and fires a dipping shot that clips the top of the Norwich bar before going over.
Liverpool warming up to the challenge now.

Alan Shearer
Former England striker on BBC One
I think Luton will play exactly the same, on the front foot, they have changed personnel but certainly not their style of play. Chelsea will create chances, can they take them?
Luton 2-1 Chelsea
Off we go for the second half.
Liverpool 0-0 Norwich
Make it easy for the keeper, eh?
Dimitrios Giannoulis chips back an awkward pass for his number one, who has to chest down and smash the ball away under pressure.
Liverpool 0-0 Norwich
Divock Origi rises to try and meet the delivery but he beats him. Liverpool keep up the pressure before Alex Oxlade-Chamberlain fires a shot from range wide.

Gary Rose
BBC Sport at Anfield
That clearance by Alisson almost sent laptops flying in the media seats. Placheta was eventually flagged offside but Alisson didn't know that and was quick off his line.
Norwich, to their credit, are not looking afraid to get at Liverpool in these early stages.
Great atmosphere on a very chilly and windy night at Anfield.
Liverpool 0-0 Norwich
Looking a bit rough in places is the Anfield turf. Not quite your classic FA Cup mud bath, but certainly not the pristine surface you expect at Premier League clubs.
Luton 2-1 Chelsea
Phil McNulty
BBC Sport chief football writer at Kenilworth Road
Well that was a bit lively. Chelsea looked like they had restored an element of normality to this FA Cup fifth round tie but Luton Town have been outstanding. The Hatters are back in front and Kenilworth Road is rocking.
Liverpool 0-0 Norwich
For a second, it looks like City's Przemyslaw Placheta might be in on goal but Alisson is quickly out to hammer the ball away.
Southampton 1-0 West Ham
Oh, nearly.
Southampton end the half on the front foot, with a Will Smallbone effort looping on to the roof of the net.
Luton 2-1 Chelsea
Alan Shearer
Former England striker on BBC One
Thirty seconds earlier Luton could have gone 2-0 up, they didn't take that chance and Saul sticks it away really well, guides it into the corner.
Liverpool 0-0 Norwich
Remember, Norwich did have the temerity to take the lead here 11 days ago. They lost the game, but they gave the Reds a scare.
Liverpool 0-0 Norwich
The final FA Cup game of the evening is under way. Liverpool gunning for part two of this possible quadruple. Can Norwich chuck a spanner in the works?
Luton 2-1 Chelsea
Micah Richards
Former England defender on BBC OneIt
It is quality, a proper cup tie.
The manager said they were going to be on the front foot and I thought they would be picked off but Luton have been absolutely magnificent.
Once Reece Burke had the run on his marker for the opening goal, he had the height too and it cost Chelsea.
