After successive league defeats to Bournemouth and Manchester City, Arsenal was knocked off the summit for the first time since October by City last week but responded to secure three vital points.

It was far from convincing, and the quality of Eze's sublime ninth-minute strike was at odds with the rest of a laboured display by Mikel Arteta's side, but all that mattered for the hosts was getting back to winning ways.

The nervousness around the stadium was apparent throughout a tight contest and there was relief when Newcastle substitute Yoane Wissa blazed a glorious late chance over the crossbar.

With Manchester City otherwise engaged in FA Cup semi-final action, Arsenal took the chance to move to 73 points from 34 games with City on 70 from 33.

"It's never going to be a path of roses," Arteta said. "We knew at half-time we wanted to score the second goal but we were not efficient enough. But we did the job."

Newcastle's fourth successive league defeat, and 13th in its past 14 league visits to Arsenal, left it in 14th place and with pressure mounting on Eddie Howe, although he said he was pleased with his side's improved display.

"I can't be too critical of the players today, it was a much better performance," Howe said.

Arsenal's stuttering run in the past month began with a tame Carabao Cup final defeat by Manchester City followed by a surprise loss to second-tier Southampton in the FA Cup quarter-finals.

But it was the back-to-back league defeats and the evaporation of a nine-point lead in the title race that has really spooked Arsenal as it tries to land a first Premier League crown since 2004.

While the performance against Newcastle will hardly have had Manchester City quaking in its boots, what is not in dispute is Arsenal's ability to capitalise from set-piece routines.

Eze's goal was the 17th Arsenal has scored from a corner this season, a Premier League record, but this was a variation on the usual routine.

Twice in the opening minutes the Gunners used a short corner rather than the usual high delivery into the area. The first two had little effect although Eze did fire a shot wide from the second.

When another corner came along soon after, the ball was played low into the area to Kai Havertz, who fed it back to Eze just outside the penalty area and in one flowing movement he curled a right-footed shot away from the helpless Nick Pope.

It should have settled Arsenal's nerves and made for a comfortable Spring evening against a labouring Newcastle whose season has hit the buffers.

In reality, it was never comfortable. Arsenal were strangely passive throughout the rest of the first half and Newcastle occasionally threatened, with Sandro Tonali's dipping low drive almost catching out David Raya.

Havertz limped off in the first half to be replaced by Viktor Gyokeres and Eze departed early in the second half.

"Muscular niggles, we don't think they are too much," Arteta, whose side faces Atletico Madrid on Thursday (AEST) in a UEFA Champions League semi-final first leg, said.

With Arsenal seemingly unable, or unwilling, to kill off the game, the anxiety levels grew in the latter stages and had Wissa shown more composure with the goal gaping, Arsenal would have handed another gift to City.

On the plus side, Arsenal showed commendable durability – Bukayo Saka returned off the bench after a month out and Arsenal will have the chance to open the gap to six points when it hosts Fulham next weekend before City is next in league action.

Arsenal's Martin Odegaard said after the match he knows how vital these three points can be for his come the end of the season.

"It was tough, very intense, very physical," he said. "We did everything we could, and we got the win. The most important thing was to bounce back with a win and get over the line with the three points.

"This schedule is crazy. We just have to keep going. It is the end of the season. Just leave everything out that we have inside, fight every single game, and we just have to keep going.

"That's where we want to be, but it is going to go all the way to the end. We are ready for it, and we will fight every single day."
