The Gunners had looked on course to lose ground on the sides above them in the race for a top-four finish but ultimately ran out 2-1 winners as Jose Sa palmed Lacazette's effort into his own net in the closing stages.

Earlier, Hwang Hee-chan had been gifted the chance to put Wolves ahead after a mistake from Gabriel Magalhaes and they appeared set to leapfrog Arsenal into fifth before two goals in the last eight minutes turned the game on its head.

Club-record signing Nicolas Pepe levelled with a smart turn and finish just 11 minutes after he came off the bench, but it was Sa's unfortunate glove which completed a comeback for Arteta's side - who now sit just a point behind fourth-placed Manchester United with two games in hand.

Arteta on Lacazette: 'For me it's his goal!'

Lacazette is out of contract in the summer but is still captaining Arsenal and Arteta felt his performance was not that of a man looking to leave the Emirates Stadium any time soon.

Arteta said: "When I see our striker in the 85th minute, chasing a full-back in the corner flag, winning the ball back, playing, going, fighting, missing one chance, missing two chances, going again. What can I do?

"I can only praise him and try to help him as much as possible and give him support. At the end he got the reward. For me, it's Lacazette's goal.

"We don't know what is going to happen at the end of the season. What he needs to do is put aside that future. It is part of our game, we don't have contracts that run for 20 years. That's part of our job and we have to be conscious of that.

"There's nothing to tell him but to praise him, because every single day he behaves like someone that wants to stay with us."

Arsenal's winning moment in pictures...

'Lacazette summed up Arsenal's character'

Lacazette endured a frustrating evening and is still without a league goal from open play since December 11 but he kept going until the last, eventually helping Arsenal over the line.

And Arteta felt his captain summed up Arsenal's resilience as they battled from behind to beat Wolves with a stoppage-time winner.

"Yes and that is what we need as a team," Arteta replied when asked if Lacazette's efforts summed up the team's display.

"Now we are building a team with a lot of young talent and new players and they need those experiences.

"I said to them at half-time, if you want to be in the top at the end of May we are going to have to overturn results maybe two, three or four times and today was an opportunity.

"I'm especially happy when a player makes an individual error that costs a goal and the team can put that aside and win the match and everybody is talking about it."

Lacazette hails 'amazing' win

Arsenal striker Alexandre Lacazette told Amazon Prime:

"I feel really happy, it is amazing to win this kind of game in the last minute.

"We really wanted this win because we know it is important to be at the top of the table.

"I knew it was the end of the game and Nicolas Pepe gave me a good ball. It went in and we are happy with the three points.

"A bit sad it is not gone down for me, I want to score, but most important is to win.

"We had a difficult January but we are coming back better in February."

Lage proud of Wolves' display

Wolves slipped to defeat, losing from a winning position for the first time in 45 matches - but boss Bruno Lage was still pleased with what he saw.

"No, no I am proud," he said when asked if he was disappointed with the loss. "The word is proud of what we did here, against this team, in this stadium.

"I think we started the game very well, we have three good chances to put the score to 2-0 to us.

"After that it is football, we tried to manage the game in the best way. Arsenal played very well and scored two goals. That is why I said I am proud.

"We played better today than we did against Leicester - but this is football, we don't win any points today."

What's next?

Arsenal's next game is away to Watford on Sunday, March 6 in the Premier League - kick-off 2pm - while Wolves travel to West Ham on Sunday, live on Sky Sports from 1pm; kick-off 2pm.
