Newcastle claimed their first win of the season as Ayoze Perez's second-half goal handed them victory against a profligate Watford side at St James' Park.

Perez headed Ki Sung-yueng's in-swinging free-kick past Ben Foster to end the Magpies' winless run and lift them out of the relegation zone.

The visitors - aiming to register their fifth straight Premier League win over the Magpies - went closest to scoring in the first half, with Adrian Mariappa and Gerard Deulofeu both guilty of spurning excellent opportunities to put the Hornets ahead.

Mariappa scuffed a shot wide moments after seeing a close-range header hacked off the line, before Deulofeu dragged a tame effort off target following a delightful through-ball from Abdoulaye Doucoure.

Roberto Pereyra rattled the crossbar in the opening minutes of the second half, but Newcastle - who lost Yoshinori Muto, Jamaal Lascelles and Jonjo Shelvey to injury before the hour mark - rallied to earn their first home points of the season.

The victory lifts Rafa Benitez's side into 17th above Cardiff and Fulham.

Magpies ride their luck

Newcastle failed to register a single shot on target against Southampton last weekend, and the Magpies struggled to create clear-cut opportunities once again on home turf, testing Foster on just two occasions.

The Watford custodian's only save in the first 45 minutes came from Mohamed Diame's long-range drive, while Salomon Rondon - making his first Premier League start since 22 September - cut an isolated figure in attack.

Kenedy broke clear of the Hornets' defence midway through the first half, but the Chelsea loanee's powerful shot was blocked by Mariappa.

The hosts improved after the break, with Perez scoring Newcastle's first home goal since a 2-1 defeat to Arsenal on 15 September.

Benitez will hope the win proves a turning point for the Magpies, who host Bournemouth next Saturday.

Wasteful Watford

Watford inflicted the Magpies' heaviest defeat at St James' Park last season, and manager Javi Gracia will feel his team should have registered another three points after a dominant performance in the North East.

The Hornets laid siege to the home goal in the first half but only managed one shot on target over the course of 90 minutes.

Deulofeu - who scored his first goal since February in the 3-0 victory over struggling Huddersfield last weekend - missed a hat-trick of chances before the break.

The former Barcelona and Everton attacker scuffed a shot wide from close range before firing harmlessly off target from Doucoure's pass.

He then drilled a low effort into the side-netting as Newcastle somehow managed to go in to half-time with their clean sheet still intact.

Pereyra was unlucky not to break the deadlock shortly after the interval with a fierce shot that rebounded off the crossbar, but it wasn't to be for Gracia's men who slipped to their fourth league defeat of the season.

What the managers said...

Newcastle manager Rafael Benitez: "In my opinion we deserved to win before today, but to do it today with the team working so hard and with the fans behind us was good.

"We had three injury problems and three substitutions but the reaction was good. It is a great three points.

"All three players really contributed, we needed energy and commitment from everyone and the three players quickly focused and did what they had to do."

Watford manager Javi Gracia, speaking to BSports: "I think in the first half we played much better, we had more chances - clear chances - and a lot of them.

"If you don't score, then from a free-kick Newcastle can score. We need to improve for the next game. I can be disappointed with the result but not with my players.

"I like to be demanding and want us to finish better, but we have played well and need to keep this level. Today was a missed opportunity but that is football."

What's next?

Newcastle welcome Bournemouth to St James' Park in the Premier League next Saturday (15:00 GMT kick-off), with Watford away at Southampton at the same time.
