Wenger has not yet signed a contract extension at the Emirates Stadium, but Vermaelen believes that the club are still moving in the right direction under his guidance.
"Everybody wants him to stay as long as he can. He's been incredible what he's done for this club, and for the players as well," The Mirror quotes the Belgian defender as saying. "We would be really happy for him signing on for a few more years.
"The spirit is unbelievable in the team. We've worked a lot on our team shape and everybody knows their role in the team, everybody's working for each other and that's because there is a great team spirit. That's the great improvement for us this season."
Arsenal are currently fourth in the Premier League with six games remaining in their campaign.
