Watford head coach Walter Mazzarri admits his team suffered a lot during the second half of their goalless draw at Swansea City.

The Hornets were put under pressure by Bob Bradley's side after the break but held on to keep their second clean sheet in a row.

Speaking to the club website, Mazzarri said: "Considering it was an away game, the first half was one of our best so far, until the last 25 metres towards goal.

“Other than that we played in the first half as I want my team to play, but we do need to be more aggressive in the last 25 metres."

He continued: “In the second half we would have loved to have played the same as in the first half but we suffered a lot and we could have been much better.

“The mistakes we made allowed Swansea to be dangerous and meant there were some moments which we had to cover.”

Watford had two claims for a penalty in the latter stages, after a handball from Kyle Naughton and a challenge on Valon Behrami, but referee Paul Tierney decided otherwise.

Mazzarri said: “I tend not to comment on referees but I’ve seen the video and maybe we were unlucky with the decisions.

“So perhaps we could have had three points, but overall I’m happy because we played in a smooth way at times and that's how I’m asking them to play.”
