Watford look rock solid. They've not wobbled, they seem organised and they have a style of play.

They're solid in midfield and you can see how they get results with a mix of creative players, experience, and the physical nature of the team.

If QPR can get off to a good start this place will be rocking, they'll be enjoying this little run and hopefully their players can get off to a quick start.

You can watch Doncaster Rovers' match with Crystal Palace on Sunday from 16:00 GMT live on BBC One.

Chelsea v Manchester United will also be shown on BBC One on Monday from 19:30 GMT.

Mumford & Sons' Marcus Mumford and Winston Marshall give football commentary a go, describing Nat Knight-Percival's bizarre goal for Bradford in the second round against Plymouth in December 2017.

This is QPR's first FA Cup fifth-round match since 1996-97 - they last reached the quarter-finals in 1994-95 before they were knocked out by Manchester United.

Matt Coupeland: Think Wolves have a good shot. They've shown they can beat the top 6 teams, they have proven winners in their European champion players to help hold the nerves as they progress towards the final, and their counter attack tactics suit cup football well. Would not bet against them.

Ollie Hayman: Brighton?...

Speaking of giant-killers... Newport County have proven they can step up to the plate this season but can they do it again?

Manager Mike Flynn tells Football Focus reporter Mark Clemmit that his side hope to pull off the "biggest FA Cup shock" of all time when they take on Premier League champions Man City on Saturday.

QPR manager Steve McClaren: "Just recently our performances have been inconsistent. We've talked about it. In the last week I've been pleased with the performances.

"We haven't had that luck recently and it will turn. We're very close - and tomorrow's game is a great opportunity."

Already this season, seven clubs from outside the Premier League have proven to be giant-killers in the FA Cup.

But which teams have been the most prolific upsetters in FA Cup history?

Using the database from sports analysts Gracenote and a definition of a giant killing as knocking out a top-flight team when not in the top flight, we discovered the answer.

Nathan: Liverpool, Spurs & Arsenal already gone. Man Utd or Chelsea will also be gone before the quarter finals. Man City also still in, but a great chance for a mid table Premier League team to win a piece of silverware. Hope they all play strong sides and go for it.

AFC Wimbledon's Scott Wagstaff has coloured his beard for the weekend FA Cup tie with Millwall.

Fair play.

Watford head coach Javi Gracia: "I think QPR are playing well. It's true in the last few games they didn't get good results but in many games they've been very close to getting them.

"Against Bristol City on Tuesday they conceded the second goal from a penalty at the end. In the game before, after losing 4-0 against Birmingham they were able to score three goals and missed a penalty in the last minute. I know it will be a very demanding game for us."

Queens Park Rangers might have lost their last game at Bristol City 2-1 but boss Steve McClaren names an unchanged starting line-up as the club looks to reach the quarter-finals for the first time since 1995.

That means striker Nahki Wells, on loan from Burnley, starts.

QPR: Lumley, Furlong, Leistner, Hall, Wszolek, Luongo, Cousins, Freeman, Bidwell, Wells, Smith.

Javi Garcia names a pretty strong Watford team at Loftus Road.

Skipper Troy Deeney is one of six players that started the 1-0 win over Everton last weekend.

Tom Cleverley is one of the five returning to the side.

Watford XI: Gomes, Janmaat, Kabasele, Britos, Holebas, Hughes, Capoue, Cleverley, Sema, Deeney, Gray.

Are Watford serious contenders for the trophy?

Owen Brayne: Not win, but defo make the final...

Stiofan: Love to see Wolves win it.

Simon Jenkins: Not Watford. No chance. Can’t see anyone but their fans rooting for them to win it! Boring boring.

Ifan Wyn Roberts: Newport would be made into a film if the unthinkable happened. All the best to them.

QPR claimed a comfortable win over Portsmouth to reach the FA Cup fifth round for the first time since 1997.

Matt Smith headed down from a corner for Nahki Wells to bundle in for the Championship side before Smith rose to head home from a Luke Freeman set-piece.

There's a few tasty ties to come this weekend after tonight's game. Check out some of the best ones.

A repeat of last year's final will be taking place on Monday!

We've got a whole load of facts, stats, records and memories from the most famous domestic tournament in the world, but it appears that not all of them are true.

Can you work out which ones aren't and which ones are?

There's a handful of big teams left in the FA Cup but one of them will be going out on Monday when Chelsea and Manchester United face off.

So that means the competition could be left wide open to an unpredictable winner.

With a decent draw, Watford surely have a chance of reaching the final given their form this season but can they go all the way? What about Wolves and Crystal Palace?

Let me know who you think could win the competition this year and whether or not Watford have what it takes? I reckon they do...

The weekend's opening tie could be a cracker, with neither side constrained by any real league pressures to go back to.

Despite an awful current run of Championship results, QPR aren't in imminent danger of a relegation scrap, and can point to a lot of bad luck of late.

They can also take heart from the form of recently-recalled Matt Smith, with the giant striker scoring four goals in the last three games.

Watford are in rude health and, if they win this as they ought to, might feel that this could be their cup year.

With no replays in the fifth round for the first time, it's all or nothing under Friday night lights at a full Loftus Road.
