Watford boss Walter Mazzarri is demanding more from his players after their 2-1 win over Burnley.

Jeff Hendrick's early dismissal proved to be the difference as Troy Deeney and January signing M'Baye Niang gave Watford a 2-0 lead at half-time.

Burnley fought back and Ashley Barnes pulled one back from the penalty spot after Hornets defender Sebastian Prodl handled the ball in the box but the hosts held on to claim successive wins in the Premier League for the first time since September.

"I'm very happy of course because we won. I liked the way we played in the first half but I'm not happy at all about the second," Mazzarri said.

"This is why I say we have to grow in mentality as a team because the big teams would have closed this game like we should.

"We could have scored three or four goals but we didn't do it and we risked losing three points for immature mistakes that could have changed the game.

"The only excuse I can find is that we played a very important game a few days ago against Arsenal where we spent a lot in terms of condition.

"Also we have many players coming back from injury who are still finding the perfect condition but we should have scored the third goal.

"Before this game I told my players that the transfer market is finished and you are the team that is going to be until the end of the season and you always have to go with the same spirit as we had at Arsenal."
