Mikel Arteta has refused to rule out a new contract for Alexandre Lacazette and says he has no concerns about the striker's motivation amid uncertainty over his future.

Lacazette came off the bench to score a late equaliser in the Gunners' 2-2 Premier League draw with Crystal Palace on Monday.

The 30-year-old forward's contract expires at the end of this season and he will be able to speak to clubs outside of England about a pre-contract agreement in January.

However, Arteta insisted the Frenchman remains a key member of the squad, praising his display against Palace and leaving the door open for fresh terms to be offered.

In all competitions at Arsenal, Lacazette has scored three goals (behind only Aubameyang) and registered one assist in just 185 minutes of football, recording the best minutes-per-goal ratio at the club with 61.67.

"[I want Lacazette to] keep doing what he’s doing, he had a good impact as well against Brighton," Arteta said ahead of the Gunners' match with Aston Villa on Friday. 

"Since I've been here he’s played a lot and been important and he will continue to be important.

"I think he was able to transmit that energy [against Palace] and that was contagious for the rest of the team and for the stadium.

"He created a different atmosphere straight away with his energy, with his quality as well and the determination that he showed to change the result. [He had] that belief in himself that he could do it.

"I had no doubts about [his motivation] and if I did I would probably have decided to do something different in the summer if the motivation was just his financial future. It's not the case with Laca and he's a really important player for us.

"Anything is possible [regarding a contract extension]."

The Arsenal boss bemoaned the fact his side dropped off after going ahead instead of attempting to extend their advantage and believes that is a mentality the Gunners need to change.

"After scoring the goal and after hitting the level of performance that we were hitting in the first part of the game, we just need to make sure that we go for the second [goal] and we continue to play with the same fluidity, with the same intention and we don't start to defend something that we have because the game is really long," Arteta added.

Bukayo Saka was forced off at half-time after being kicked in the calf by Palace midfielder James McArthur and Arteta says he has not trained ahead of the upcoming Premier League fixture.

The Gunners boss believes the offending player should have been sent off instead of being shown a yellow card and does not understand why the VAR did not step in.

"We had communication with the referees and the associations to try to explain why they didn't intervene [when McArthur kicked Saka] when the explanation at the start of the season is that they would when there's an obvious error," Arteta continued. 

"They had to take action and they didn't and there are actions that determine a football match and the result. For me, it's not acceptable."

Arsenal face Villa at the Emirates Stadium on October 22 as they look to close the three-point gap between themselves and the top six.
