Arsenal academy chief Per Mertesacker admits he's been overseeing major changes since taking charge.
Was appointed academy boss upon retirement at the end of last season.
“Any change has risk but also chances," Mertesacker told the London Evening Standard. “We're seeing the chances now. There's a lot of energy in this place: first team, Academy, women's.
“We're really happy with the new appointments no matter where they are. That everything connects in a proper way really takes time. When you have positive results that helps but you still need that time.
“Last season I had a good look at everything [around the academy] because I didn't play regularly anymore. I was just training, obviously seeing young players with the first team. I could have a good guess [what it would be like].
“But being in there full-time means something different. You have to put your presence in there and your full effort. You cannot just slide by and think people are doing the job for you. This takes complete effort and that's what I'm giving."
