Chelsea v Manchester United (19:45 GMT)
I've seen graphics so far showing Phil Jones as a right-back, centre back in a back three, and a midfielder.

Moon: Very likely an all-London semi, has to be at Wembley?? But it should be saved for the final... money talks sadly.
Chelsea v Manchester United (19:45 GMT)
'We are tired, but we want to win," says Jose Mourinho on his return to Stamford Bridge.
He also says that he can't explain his formation. Total fussball!
Full quotes to follow.

Trev has gone CAPITALS about the capital.
Need the top teams at the end of the competitions. We've had the romance and it's been great but now we need quality competitive matches.

Should be final only at Wembley. Yes more fans may be to see their team in a semi final but there was a special buzz about two outsiders playing at a club ground. Villa Park had a unique atmosphere on semi final day.

I'm of an age that remembers FA Cup semi-finals being played at neutral venues midway between teams, it held my passion for the Cup. Now it's all gone, NO to Wembley semis.
Trev. Northumberland.
Chelsea 4-0 Manchester United
Jose Mourinho was humiliated on his return to Chelsea as his former club blew away his Manchester United side at Stamford Bridge in October.
The Blues, who sacked Mourinho for a second time in 2015, led after just 30 seconds when Pedro capitalised on slack defending to roll in.
Gary Cahill smashed in the second after United allowed Eden Hazard's corner to bounce in their box.
United offered little sign of making a comeback, falling further behind when Hazard drilled in a precise 15-yard strike.
N'Golo Kante skipped around a static defence to slot in and seal victory.

Chelsea
We don't know what formation Manchester United are playing, answers on a postcard.
Here's the Chelsea team though: just the two changes from the win at West Ham.
In come Nemanja Matic and Willian for Pedro and Cesc Fabregas.

CW Kinsey: Playing the semis at Wembley devalues the magic of making it to the showcase finale. FA Cup feels less special, this doesn't help.
Sho Rahman : Going with the 3-5-2 then very interesting. Relief that Rashford is fit. Not sure about the Young selection though

Watch some of the best goals from past FA Cup meetings between Chelsea and Manchester United, including a classic header from Norman Whiteside in the fourth round in 1988 and Didier Drogba's deft flick in the 2007 final.

Marcus Rashford's sickie comes to no avail - he starts for Manchester United. They make four changes from the team which drew in Rostov.

With this final FA Cup quarter-final about to get under way at Stamford Bridge, Manchester City, Arsenal and Tottenham wait in the velvet bag.
Whoever wins tonight, it's going to be four of the top six in the last four.
Is that a good thing? Is it better for the competition to have all of the big names facing each other at Wembley?
Or is it a blow to the 'romance' of the old cup, despite the exploits this year of Lincoln, Sutton and co? Did you prefer the Cardiff v Portsmouth final a few years ago?
Should the semis even be played at Wembley (opens can of worms...)

Speaking of legends, Fabio Capello and Ruud Gullit were chewing the fat on the sidelines a while ago - what a great Milan side they both graced as manager and player respectively.
Chelsea v Manchester United (19:45 GMT)
New rules for this season: no replays from the quarter-finals onwards and a fourth sub who can be used if we go to extra time.
Keep your eyes peeled. We may get a little bit of history tonight.

A Chelsea legend.
Here's what Frank Lampard had to say about tonight's game a little earlier.
Chelsea v Manchester United (19:45 GMT)
We should have confirmed team news soon.
Wayne Rooney collided with Phil Jones in training (not something I'd recommend) and misses out with a leg injury, while Zlatan Ibrahimovic begins a three-game ban for elbowing Bournemouth's Tyrone Mings.
Anthony Martial is also injured, while Marcus Rashford has been under the weather.
The precise nature and severity of the leg injury Rooney has sustained is not known but the England captain was unable to complete the training session and will have a scan on Monday.
No blame has been attached to Jones for the incident in what has been described as a "full-blooded session".
It had been expected that Rooney, 31, was going to be involved because he did not go to Russia for the Europa League last-16 meeting with FC Rostov on Thursday.
Chelsea v Manchester United (19:45 GMT)
With Zlatan Ibrahimovic banned, Wayne Rooney and Anthony Martial injured, and Marcus Rashford reportedly as sick as a dog, tonight's FA Cup quarter-final at Stamford Bridge was lining up to feature the spectre of Marouane Fellaini playing up front for the holders.
What a sight.
But then Rashford went and ruined it all by making his way down to London after all.
Chelsea v Manchester United (19:45 GMT)
It has been seven years since a team completed the Premier League and FA Cup double.
It has been seven years since Chelsea completed the Premier League and FA Cup double.
Tonight Chelsea face cup holders Manchester United as they look to take a considerable step towards ending that wait.
Let's not get carried away - even with a win tonight they would have to face Manchester City, Tottenham or Arsenal in the semis.
But with a 10-point cushion in the league and no European football to worry about, the title looks in the can.
Their record against Manchester United is excellent, they have only lost twice since September and they have a fully-fit squad available.
Antonio you require: A win...
