Heurelho Gomes runs over to the away fans and thumps the badge on his chest. The atmosphere is "rocking" that's for sure.

And we're off! Predictions?

Before we start, there is a minutes applause in tribute of goalkeeping legend Gordon Banks.

Sydney Bevan: What about AFC Wimbledon?

It's the biggest game of the season for QPR tonight.

It's a massive moment for them, the fans are up for it. It's a big night in their season and the supporters are really going to get behind them here.

Right. Back to business. Birthday party later.

The players are out on the pitch and we're almost ready for kick-off. I have a feeling this is going to be a good game...

Watford midfielder Will Hughes speaking to BT Sport: "It is one of the best runs I have been on. It is a good chance for us tonight.

"There is something special about it [the FA Cup] with the teams who play in it. I'm not taking it for granted tonight.

"A lot of the Premier League teams have been knocked out by lower league opposition. It's a big chance for us tonight but they will be thinking the same.

"The atmosphere is quite intimidating. It's a close stadium to play in and there's a different style of football to the Premier League. We know the tasks in hand and we know their strengths."

If anyone else is aware of any birthdays we may have missed, speak up now!!

An anonymous source has just sent us a text with potentially the fact of the weekend! We've checked it and they're right. Amazing.

QPR striker Nahki Wells speaking to BT Sport on his experience in cup competitions: "I have been fortunate to play in a domestic cup final, some play-offs and in some big games.

"So hopefully we can go one step further and beat a Premier League team on our home ground tonight.

"The crowd play a big part. I think they know that. They have proved the difference so tonight will be massive.

"They will be our 12th man and it should be rocking tonight."

Chance for the likes of Watford's Tom Cleverley and Andre Gray tonight. They haven't started too many games of late but you'd expect them to take their opportunity.

Troy Deeney will no doubt cause problems too.

1877Wolves: You can’t look beyond Man City. There’s favourites .... then there ridiculous favourites.

Watford have only lost two of their past 13 matches in all competitions, winning six and drawing five.

They have won seven of their last eight FA Cup ties against sides from a lower division.

QPR manager Steve McClaren speaking to BT Sport: "We have to compete. We need to stay in the game. The key is [Troy] Deeney and [Andre] Gray up front. Can our backs handle them?

"In the front two we have an outlet. The first thing is making sure the Watford players know they will be in a game. We want to be putting crosses into the box.

"We have been inconsistent. We made four good loan signings and three of those are injured so that has been a big loss for us. But in the FA Cup anything can happen.

"I said to the players they are going to have to work hard tonight. The first 15 minutes are going to be vital in this game. It's over 95 minutes and then whatever happens!"

There she is! The FA Cup is at Loftus Road tonight.

Remember when Matt Smith bossed it against Everton and Liverpool when he played for League One side Oldham in the 2013 FA Cup?

He starts for QPR this evening.

AJ: Bristol city obviously.

Barts: Bristol City don't know how to lose.

Jake: No.. because Solskjaer's at the wheel.

Andre Gray and Isaac Success were on target as Watford edged past Newcastle to reach the fifth round.

Gray converted Will Hughes' smart pass on 62 minutes for his fourth goal of the season and Success finished off a counter-attack to seal the win in stoppage-time.

It's Watford keeper Heurelho Gomes' birthday today! He turns 38. I reckon sealing a place in the quarter-finals would be a pretty good gift.

He's just being warmed up at the moment and he looks more youthful than me. He's more than a decade older...

Watford manager Javi Gracia speaking to BT Sport: "We tried to choose the best option. We want a good performance. We have changed some of them but the squad is ready and they all deserve a place.

"There is no secret. When you have good players and you work hard like they are you have options to compete well.

"The players have high commitment. The difference in the level that both teams are playing is not much. In this stadium playing against QPR you have to defend well against set-pieces.

"We have to be ready for that."

Ope: Birmingham won the League Cup and got relegated, ditto for Wigan after winning the FA Cup. Why not Watford? after all they have a certain Success (no pun intended) in their books.
