Walter Mazzarri believes Watford subs made the difference in 3-1 win over Manchester United

Watford manager Walter Mazzarri hopes his side 3-1 victory over Manchester United on Sunday (18 September) will give the Hornets a boost for the rest of the campaign.

The Italian boss admitted his side felt the pressure following Marcus Rashford's equaliser, but the introductions of Nordin Amrabat, Isaac Success and Camilo Zuñiga made the difference to help his side to recover to control of the game and secure the three points.

The Hornets enjoyed a slow start to the life under the Italian boss following two consecutive home defeats against Chelsea and Arsenal. However, after an away win over West Ham last weekend, they managed to beat United to secure their first three points of the campaign at Vicarage Road.

Etienne Capoue's gave Watford the lead in the 34th minute of the game with his fourth goal in five Premier League games before Marcus Rashford equalised after the break. United looked then in line to fight for the victory, but two late goals from substitute Zuñiga and Troy Deeney gave the three points to Watford instead.

"It is a very important three points to give my players the confidence to go ahead," Mazzarri said to BBC after the game. "We were playing well, we conceded a goal and we stopped playing and we were afraid, but then we made the changes and everything went the right way. It is something we need to work on."

The Italian boss was delighted about the result, as it was also Watford's first win over Manchester United in 30 years. Yet, he hopes that the three points will help them ahead of the coming games, starting with a Premier League trip to Burnley on the weekend.

"We have been improving, I don't look too much on results but how we play and we have been improving dramatically," he aded. "We're playing well but now we have to look ahead to the Burnley game on Monday and focus again."
