Pierre-Emerick Aubameyang's first-half brace looked to have put Arsenal in total control at Vicarage Road on Sunday.

But a defensive error gifted Watford a lifeline through Tom Cleverly, and Roberto Pereyra's late penalty earned them a share of the points.

"Coming in at halftime I would have snatched your hand off for 2-2, but with five minutes to go there was only one team that was going to win it," Cleverly told Sky Sports.

"We can definitely build on this and go forward."

Despite the comeback, Watford remain winless and bottom of the table while Arsenal stay seventh.

Arsenal opened the scoring in the 21st minute when Aubameyang took a pass from Saed Kolasnic, turned and fired a shot inside the near post.

The Gabon international then tapped in 11 minutes later to make it 2-0.

Watford were allowed back into the game in the 53th minute by a calamitous error as Arsenal tried to play a goal kick out and Sokratis Papastathopoulos' pass was deflected to Cleverly, who drilled a shot past Bernd Leno.

Watford then turned up the pressure and were rewarded in the 81st minute with Roberto Pereyra's penalty after he was fouled by David Luiz.

The Hornets then had a final chance for a late winner but Abdoulaye Doucoure shot straight at Leno after being left alone in the area.

"They pushed us," Arsenal manager Unai Emery told the BBC.

"We were up in the first half and we knew that we needed to score the third.

"They had the capacity to come back with the supporters and that's what happened."

Earlier, Callum Wilson scored twice as Bournemouth beat Everton to climb into the top half of the table.

Wilson headed Bournemouth into the lead at Vitality Stadium only for Dominic Calvert-Lewin to equalise with a header of his own before halftime.

The Cherries then clinched their first home win with two goals in a five-minute span of the second half as Ryan Fraser's free kick deflected in off Fabian Delph, and Wilson lobbed Jordan Pickford.

The win lifts Bournemouth to eighth from 16th, while Everton drop three spots to 11th.

"It is huge psychologically because our home form is so important," Bournemouth manager Eddie Howe said.

"We knew it was a huge moment in our season and hopefully we can use it as a launchpad for better things."

West Ham will look to crack the top three when they travel to Aston Villa on Monday night.
