Dennis Bergkamp says he is impressed with the changes Mikel Arteta has already introduced as Arsenal boss - but stressed that more improvements are needed.
The Gunners legend was in conversation with fellow Invincible Martin Keown when the subject of Arteta's management was brought up.
Bergkamp felt Arteta's change in style was noticeable even from his first home game in charge, a 2-1 defeat to Chelsea.
Yet the former attacker also argued that the team clearly need more time to become a cohesive unit.
"I watched Arteta’s first game in charge at home," Bergkamp told the Daily Mail.
"In that game it was clear to see what his intentions were with the team.
"The front four would chase the ball and put pressure on the opponents, but the midfield stayed behind. There was a big hole.
"I don’t know if you remember the AC Milan of Arrigo Sacchi, with Marco van Basten, Ruud Gullit and Frank Rijkaard.
"In training, they’d have ropes between them, so the distance between the players was always similar on the pitch.
"That was fantastic in our team as well. There was always a connection. There were no holes."
When Keown asked what Arteta can do to plug the gaps, Bergkamp said it was a case of time, and maybe new signings.
The Dutch legend said: "He’s working on it, but it needs time and maybe different players.
"Slowly you can see them trying to play a possession game.
"Everyone on the ball has three options, triangles on the pitch. It’s much better than before.
"But it’s a different culture which will take time.
"You have to put the hours in, like how we did with Arsene."
