Mikel Arteta wants Arsenal to tie Shkodran Mustafi down to a new contract.
The German defender has been performing well under Arteta since being brought back into the fold by The Gunners’ boss.
His current deal is due to expire at the end of next season, but Arteta is hopeful the club will sort an extension before then.
“That’s something the club has to address but he knows my opinion,” said Arsenal ’s head coach.
“I’m really happy with him as you can see. The way he’s playing, how committed he is with everything we’re trying to do, the level in his performance ever three or four days, he’s been really consistent.”
Mustafi looked certain to leave under Arteta's predecessor Unai Emery, with the Spaniard having publicly said it would be better for his career if he moved elsewhere following a series of high-profile errors.
But the 28-year-old has started 15 of Arsenal's last 17 games under Arteta, helping the Gunners keep six clean sheets during that run.
Mustafi is expected to start again for Arsenal when they visit Tottenham in Sunday's North London derby.
The game could have a huge bearing on qualification for next season's Europa League, with Arsenal currently eighth - one place and one point ahead of Tottenham.
With Jose Mourinho having taken over from Mauricio Pochettino as Tottenham boss late last year, both teams are in transitional periods and would want to be higher in the table.
But Arteta said his side have a long way to go before they are competing with the Premier League's top two, Liverpool and Manchester City.
“The level of the two top teams in the league has raised so much in a very short space of time," he said in quotes reported by Goal.
“There are many reasons you can analyse but the gap has become so big in the past two or three years that we all have to make good decisions and good work to catch up and make the distance much smaller.
“And don’t think it is just one or two clubs. It is a lot of clubs that are trying to do that at the moment.”
