Sheffield United have got Billy Sharp and Rhian Brewster on the bench.

How long before Paul Heckingbottom looks to make a change?

Watford's front three of Emmanuel Dennis, Ismaila Sarr and Joao Pedro all played a part in that opening goal.

They could well light up the Championship this season.

Sheffield United boss Paul Heckingbottom is booked for protesting following that goal.

It might have been over the potential offside, or for a foul in the build-up. Either way, his side are a goal down.

Enda Stevens can't continue and Max Lowe comes on for the Blades.

Enda Stevens is down once again for Sheffield United.

A bit of cramp maybe or a strain? It seems to be in his calf. He's off the field receiving treatment as the game goes on.

That's a bit silly from Watford striker Joao Pedro.

The Brazilian sticks an arm in the face of Enda Stevens and is booked.

There's definitely been a bit of spice in this match.

The hosts get things going again. Rob Edwards will want to see his Hornets side start it with the same intensity they began the first...

The teams are on their way back out at Vicarage Road.

Who's going to make the difference?

Both teams looked well matched in those first 45 minutes.

It's probably to be expected as they're two of the favourites to go up this season.

Watford started really brightly, but the Blades grew into the game as the half wore on.

All to play for after the break.

An entertaining, but goalless first half comes to an end at Vicarage Road.

Tom Cleverley appears to slip into Illiman Ndiaye but the Watford captain is booked. Looked a little harsh to me.

Sheffield United carve out an opportunity on the counter-attack!

George Baldock sprints down the right and sends in a wonderful low pass to Daniel Jebbison on the edge of the box.

The teenager curls it first time towards goal and his dipping effort is tipped over the bar by Daniel Bachmann.

That's a fine save by Wes Foderingham!

Ken Sema sends in a lovely cross from the left and Watford striker Joao Pedro meets it with his head, but Foderingham dives to his left to claim the ball.

Probably Watford's best chance of the half.

A goal before half-time would be nice...

The best chance of the game falls to the visitors.

Iliman Ndiaye goes shoulder to shoulder with Hassane Kamara just inside the box and manages to get away from the Watford defender.

But Ndiaye's low shot lacks a bit of power and is saved by Daniel Bachmann.

Enda Stevens is caught late by Watford defender Ken Sema and requires a bit of treatment.

He's okay to continue though.

Edo Kayembe has a go from distance for Watford but his shot is blocked by a defender and loops out for a corner.

With half-an-hour gone Rob Edwards might be a bit disappointed his side aren't a goal up but Sheffield United have defended well.

It's all kicking off!

Francisco Sierralta and John Fleck square up to each other after Sierralta had taken out Illiman Ndiaye - there's plenty of pushing and shoving and grabbing before it calms down.

Both men are booked.
