Millwall 1-0 Leicester
There are still plenty of fans on the pitch at the Den, despite requests for them to depart. I think this is what you call basking.

The kettle is on in the Huddersfield press room, just waiting to hear from the managers now

I'm not sure if Antonio Conte has been versed in just how special the double of league and FA Cup is in England - but this season is a wonderful opportunity for Chelsea to join Manchester United and Arsenal as the only clubs to have achieved it more than once.
Not being in Europe and having such a cushion at the top of the Premier League offers Conte the opportunity to select a team designed to minimise the risk of an upset.
Wolves have already done spectacularly well to win at Stoke and Liverpool on their way to this, their first fifth-round tie since 2008.
They deserve a full house and a cracking Molineux atmosphere to celebrate those achievements, but celebrating another Premier League scalp looks less likely.
Wolves v Chelsea (17:30 GMT)
Chelsea have made seven changes from the side that drew with Burnley on Sunday, with John Terry in the starting line-up.
Chelsea XI: Asmir Begovic, Kurt Zouma, John Terry, Nathan Ake, Victor Moses, Nathaniel Chalobah, Cesc Fabregas, Pedro; Willian, Diego Costa, Eden Hazard.
Wolves, meanwhile, have made five changes after their defeat by Wigan Athletic on Tuesday, with Conor Coady and Andi Weimann among the players starting.
Wolves XI: Carl Ikeme,Jon Dadi Bodvarsson, Andi Weimann, Dave Edwards, Helder Costa, George Saville, Jack Price, Matt Doherty, Kortney Hause, Danny Batth, Conor Coady.
Plenty of upsettage already and one game to come...

Naveed Afzal: Huddersfield MAGNIFICENT! Leicester an EMBARRASSMENT! Middlesbrough FORTUNATE! Lincoln in DREAMLAND!
Millwall 1-0 Leicester
Millwall have done it again! Fans pour on to the pitch to celebrate another cup upset. This is the biggest of the lot, though. The Premier League champions are out. Millwall are into the last eight.

Manchester City were intending to take advantage of an unscheduled break in the fixture list by heading off to Abu Dhabi later this week.
Their trip might be a bit shorter now given they have a replay date against Huddersfield next Tuesday or Wednesday to fit in.
Millwall 1-0 Leicester
Leicester desperate. We've played four minutes of added time. They have the ball but Millwall are dug in.
Middlesbrough 3-2 Oxford
Huddersfield 0-0 Manchester City
We go again.
Shaun Cummings
Would. You. Believe it?! Millwall have played for nearly 40 minutes with 10 men against the Premier League champions but they are heading to the last eight!
Shaun Cummings cuts in from the right side, past a Leicester defender in the box and finishes low past Ron-Robert Zieler. The Den goes absolutely berserk!
Leicester's season goes from bad to worse.
Millwall 0-0 Leicester
Albrighton swings over the Leicester corner but straight into the grateful grasp of home keeper Jordan Archer.
Huddersfield 0-0 Manchester City
Three minutes added on. It's looking like a replay.
Millwall 0-0 Leicester
Final minute at the Den. The 10 men of Millwall are holding on. Leicester have a corner, though...

Former Leicester and Man Utd forward on Final Score
That was just down to a little bit of tiredness and the lack of that little bit of nous to see the game out.
Huddersfield 0-0 Manchester City
Into the final minute...

Time ticking away from anyone to find a winner.
A replay - if required - would be in the middle of the week after next.
That would mean the Manchester derby between City and United at the Etihad Stadium, postponed from next weekend due to the EFL Cup final, is unlikely to be played until the end of April at the earliest.
Apart from the replay week, there are only two free midweeks not already being used by European dates, internationals or league games from now until the end of the season.
