Ash: How many of those complaining about Salah's penalty being soft are Chelsea fans that have just benefited from two penalty decisions?

Paul: Martin Atkinson is a disgrace. Doesn't give Watford a definite penalty for a foul by Luiz yet has no hesitation in giving Chelsea one. Get VAR on and end this big club bias.

Eden Hazard has been directly involved in 19 goals in the Premier League this season (10 goals, nine assists); the most of any player in the competition.

Watford have it all to do once more.

Abdoulaye Doucoure intercepts N'Golo Kante's pass and tries setting Gerard Deulofeu free, but there is too much on the pass and Kepa Arrizabalaga is quickly off his line to smother the ball.

Good, sharp goalkeeping.

Watford will feel very aggrieved, not for that foul on Eden Hazard because it was a stonewaller, but the one at the other end which they did not get.

Eden Hazard knows exactly where the goalkeeper is and he leaves his body out, waiting for the contact.

It is a very slow run up and he waits for Ben Foster to move first.

Ash: David Luiz makes a habit of leaning into players til they fall down. He never plays the ball so how do refs not give that as a penalty?

Javel: Watford are not the rich, prestigious club here, expected to win every game. Someone should tell them!

A coming together between David Luiz and Gerard Deulofeu again.

The Spanish winger zooms past the Chelsea defender into the box, Luiz comes across with his arm and bundles him over, but referee Martin Atkinson points only for a goal kick.

How is that NOT a penalty?? Unbelievable.

Chelsea goalkeeper Kepa Arrizabalaga's kicking is not the best, he has given it straight to a Watford player on a couple of occasions now but been bailed out by his defenders.

This is the world's most expensive goalkeeper remember.

Troy Deeney is fired up for Watford, rousing the crowd with a glare.

The Hornets have had some neat passages of play at stages in the game.

After Eden Hazard got the goal, you would have thought Watford might play higher up the field - but then they equalised, and it looks like it might be back to square one.

However, it actually looks a bit more open at the start of this half, which bodes well for supporters.

Chelsea applying the pressure early in the second half.

David Luiz almost picks out N'Golo Kante with one of those trademarks balls over the top, but the little Frenchman cannot collect.

Away we go for the second half.

Both were there before Javi Gracia joined Watford, G.

Roberto Pereyra has scored three goals against Chelsea in three Premier League appearances - more than against any other side in the competition.

Jeremiah: Chelsea score and then go into a sleep mode thinking it is half time! Watford had other ideas and Roberto Pereyra strikes a magnificent world class goal. That's a Hornet's sting.

Erik: 45 minutes of grown men aimlessly kicking a ball around followed by 4 minutes of exciting football. Glad I didn't go and get an early half time pie.

The volley from Roberto Pereyra is great and it is straight off the training ground.

It is not a fluke but he has to keep it down and he puts it into the corner.

To be fair, you have to say Watford deserve it for the effort they have put in.

Zero shots on target in 45 minutes, then two goals in added on time in the first half.

That's more like it.
