Yohan Cabaye's penalty enough to help Crystal Palace beat Watford
Yohan Cabaye's second-half penalty proved enough to earn Crystal Palace all three points at Vicarage Road as Watford lost at home for the first time this season.
In a repeat of their 2013 play-off final encounter, a penalty was enough to decide the game in favour of Palace - who move up to sixth in the Premier League following the 1-0 win.
The game was evenly matched in the first half and both sides saw efforts come off the woodwork before substitute Wilfried Zaha was brought down in the penalty area by Allan Nyom - with Cabaye converting for his second Palace goal.
After a mundane start it was the visitors who created the first meaningful chance of the day as Brede Hangeland met Cabaye's whipped free-kick only to see Heurelho Gomes save from point-blank range.
Almen Abdi was booked for tripping Yannick Bolasie and, from a free-kick in almost exactly the same position as his previous delivery, Cabaye again produced a tempting cross but Dwight Gayle could not get anything on it.
Despite having plenty of possession it was not until after the interval that Quique Sanchez Flores' Watford side came close to getting on the scoresheet when, after Abdi had been tripped by Joe Ledley, Jose Jurado stepped up and hit a 25-yard free-kick that came back off the crossbar with Wayne Hennessey beaten.
The Wales number one was forced into action shortly afterwards as Craig Cathcart's accurate long ball found Troy Deeney, whose pass was chested into Abdi by Ighalo - with the full-back's driven shot not far enough away from the Palace stopper.
The visitors alleviated the pressure by hitting back on the counter-attack, with Gomes forced to push a deflected Bakary Sako free-kick behind for a corner before Gayle turned a cross from the former Wolves man against the frame of the goal - with Cathcart doing just enough to put the striker off.
Palace boss Pardew introduced Zaha from the bench after hooking him off at half-time in last weekend's defeat at Tottenham and the winger was soon involved, bewildering Nyom with his pace before being tripped by the right-back right on the edge of the Watford box.
Referee Anthony Taylor got the decision to award Palace a penalty correct and Cabaye stepped up to dispatch with aplomb and put the Eagles ahead.
Gayle should have wrapped up the points with a little over 10 minutes remaining but he could only poke wide from close-range following Bolasie's knock-down from Zaha's cross.
He came close again after staying onside and breaking clear to latch onto Bolasie's pass but, after wriggling free in the box, he arrowed a shot just wide before being replaced by Fraizer Campbell.
Watford rallied at the death but Ledley's brave block from Jurado's driven attempt summed up their afternoon and, after conceding at home for the first time since their Premier League return, they could not find an equaliser to take a share of the spoils.

Yohan Cabaye: Not many stand-out performances on an afternoon of little quality but Cabaye's coolness from the spot earned his side the win. He also produced a couple of dangerous set-pieces in the first half and his unquestioned quality almost shone through the mire of this meeting.
MOMENT OF THE MATCH
Wilfried Zaha: Hammered by Alan Pardew following a first-half to forget at Tottenham last weekend, the former Manchester United man was relegated to the bench at Vicarage Road but came on with the game at a stalemate and instantly ruined Allan Nyom's afternoon. Ran him ragged and earned the decisive penalty when tripped inside the box, with Quique Sanchez Flores reacting by hauling off his full-back soon after.
VIEW FROM THE BENCH
Pardew called for a two-game losing streak to be brought to an end and will be pleased to have taken three points from a Watford team who have already shown they will be hard to beat at home. He also did the right thing dropping Zaha to the bench - with the winger having the correct impact when thrown on. Flores made changes but will not have enjoyed losing his unbeaten home record as Hornets boss.
MOAN OF THE MATCH
While unable to match the level of boredom the Sunday stroll between Watford and Southampton produced here earlier in the season, this match, particularly in the first half, lacked both energy and quality.
WHO'S UP NEXT
Bournemouth v Watford (Premier League, Saturday 3 October)
Crystal Palace v West Brom (Premier League, Saturday 3 October)
Alan Pardew hailed the resolve of Wilfried Zaha, who was publicly rebuked by the Eagles boss after being hauled off at half-time in the defeat to Tottenham last week.
However, the former Manchester United winger earned the penalty that decided the game shortly after being introduced from the bench.
Pardew told Sky Sports 1: "I knew that if he was fresh coming off the bench he would cause a problem or two because he's got that kind of determination to prove that I'm wrong, I like that.
"He did really well and when he starts, it's about having that concentration all the time."
Pardew was also quick to pay tribute to his side's focus at Vicarage Road and was delighted they were able to put narrow defeats to Spurs and Manchester City in recent weeks behind them.
He added: "Sometimes as a manager you want a performance that really lifts you and this lifted me today because our concentration levels were really, really high. The back four were terrific, they didn't give Watford too much daylight at all today, but it didn't take away from our threat.
"We got ourselves a really great win in a tight game because we'd lost two tight games and we didn't really deserve to lose in my opinion, particularly the City game, so it's like drawing at City, drawing at Spurs and drawing here that would be fantastic.
"If we keep going for the wins, it makes up for those games where the margins cost us, so it was very important we won today and I'm very pleased."
Watford boss Quique Sanchez Flores admitted Palace caused the Hornets some problems but thought the penalty decision was harsh.
He told BBC Sport: "It was difficult to stop their attack, it was uncomfortable for us. We need to open up the pitch more.
"We did not stop the counter-attack, we were disorganised. It was a very big decision from the referee to decide the match. I am not sure."
