What a start it almost was for the Lions. Steve Morison's low cross across the penalty area was flicked onto the bar by Lee Gregory after just 17 seconds.

Just as I mention him, Adlene Guedioura will make the most of the space and time he's being given in midfield to hit one from range. That's a daisy cutter and well wide, drawing cheers from the home fans.

Adlene Guedioura seems to be seeing a fair bit of ball deep in Watford's midfield, he seems less pressed than his team-mates when he has it but as soon as the more attacking Hornets players get hold of it they get hassled quickly.

Younes Kaboul starts an attack deep in his own half but Jake Cooper is on hand to clear into touch when Abdoulaye Doucoure tries to attack down the right.

Championship side Fulham make four changes from the side beaten at Reading in midweek, as Marcus Bettinelli, Denis Odoi, Ryan Sessegnon and Lucas Piazon all come in. Chris Martin - who has missed two penalties in the last two games - starts up front.

Hull make six changes from the team which beat Manchester United, on the night if not on aggregate, in the League Cup.

David Meyler, Harry Maguire, Tom Huddleston, Sam Clucas and Adama Diomande keep their places. 

Roger Federer has just won the Australian Open if you're interested. A man of grace and elegance offers a rich contrast to what we are seeing at The Den where bite and muscle are the order of the day so far.

All the reaction to that here.

It's direct and physical from Millwall. Long balls forward are competed for in Watford territory and second balls are contested like the sack race at school sports day. 

 Adrian Mariappa at the heart of Watford's defence is going to have to head a lot of balls today, as will Younes Kaboul.

Watford are OK passing it out from the back but when they get into the middle of the pitch Millwall are all over them and not giving any time on the ball.

Shaun Williams, already taking his third corner, a floated ball... Jake Cooper meets it flush... headed wide. A chance. Some 12 yards out he had the run on his man.

All Millwall.

There are plenty of blue seats on show at The Den, it's by no means full but those here are doing their best to make it hostile. Lions boss Neil Harris scribbles on a notepad, he must be pleased with what he's seeing.

Tony Craig has a dig from 30 yards and another corner comes as Costel Pantilimon tips the looping shot over.

Shaun Williams clips the corner in but a header at goal draws a deflection to force another. In it comes again, back post this time... foul on Costel Pantilimon and Watford can breathe again.

Adlene Guedioura shows some neat feet in midfield for Watford to finally buy his side some breathing space and they can construct a few passes, take the sting out of things. 

Eventually it breaks down and Millwall attack down the left, it's direct again... Steve Morison will cross... corner.

Neil Harris stands hands in pockets on the touchline. He clapped with pride at that fast early start from his players. Watford are trying to settle but possession turns over in midfield again and Millwall go direct towards the head of Steve Morison.

That would have been a sensational start. 

Gregory has got to stick that one away. He makes decent contact but a little bit too much height.

Millwall strike the bar in the first minute. Talk about getting in the face of the big boys. It's a quality low cross from Steve Morison and Lee Gregory does everything right to steer the ball onto the bar from 10 yards. He probably should have scored having found the space...

A huddle for the Watford players, final words, Millwall's XI just stares over the half-way line. Here we go...

Thomashollern: Watched an episode of The Bill this morning and it was filmed at ''The Den''... is it an omen??

Gary Davis: Let em all come down to The Den!

James Falkingham: Well. This is a big one isn't it? 

As the songs whip around this stadium what must Watford full-back Brice Dja Djedje be thinking? Just his second game in English football and I think it's fair to say the mood and surroundings are unforgiving. Millwall want to stun the visitors, Brice best suit up and switch on.

Somewhere in the top 10 and a run in the FA Cup. 

If you are not going to the win the league you have got to aim for a cup final.

That's the spirit.

Millwall are very confident and are playing well.

This is a perfect time to be playing a Watford side who have made so many changes.

It is a great opportunity for Millwall today.
