Jack Wilshere has hailed the "intense" training sessions that Mikel Arteta delivers at Arsenal after joining the club's academy coaching staff.
Wilshere spent five months training with Arteta's senior squad at the Gunners while a free agent. While he did not play in any competitive games for Arsenal, he attended most of their training sessions in that time, even flying out for their winter training camp.
The time at Arsenal allowed Wilshere to maintain his fitness while he searched for a new club and also gave him a unique insight into Arteta's style of management. That insight is now being shown the general public through Amazon's All Or Nothing documentary series.
Arteta has developed a reputation for his intense personality and creative approach to training sessions thanks to the series. And Wilshere has insisted that what is seen on the show is exactly how Arteta is when the cameras are switched off.
"I watched the first one last night and it was really good. I've watched the All or Nothings for all of the clubs and I think it's a really good insight for fans but also for people like me who are learning to be a coach," he told the Daily Mail.
'"Playing with him, he was a guy who was very focused, very intelligent with the way he trained. As a coach he is very similar. He is very intense, very hands on with the players and trying different things, new techniques to try to help them. I like it. He's a modern coach. Sometimes it will work, sometimes it won't. You've got to try these things to see that."

Wilshere has now joined the coaching staff in the Arsenal academy set-up, having retired from playing in July. And it appears that Arteta has played a big role in developing his tactical philosophy.
"I had conversations with a few people about keeping on playing, but I was so interested and intrigued in the coaching world. I spent a bit of time coaching in the academy at Arsenal last season and I fell in love with it. The more I was there, the more I learned and the more that I wanted to throw myself into it," Wilshere added.
"So my thoughts on wanting to be a coach started before I went to Denmark. While I enjoyed my time out there, I also spent a lot of my time studying coaching and thinking about coaching.
"Once you start doing that, you have to commit yourself one hundred per cent to it. The opportunity at Arsenal came up and I put my name forward. I've got a goal of being a manager and this is a good place to start.'
"What I've learned in a short period is that a big part of being a successful coach is being able to adapt to the players that you've got. I'm blessed at Arsenal that we've got really good young players who can master the ball and keep possession.
"But it's also important to be good out of possession, be aggressive and play with passion. I like to think I was a player who played with a lot of heart and I want my team to do that. That's just as important as being good on the ball."
