Former Arsenal boss Arsene Wenger admits he's missing regular coaching.
Wenger, who took part in Per Mertesacker's testimonial, admits he's planning to return to the bench this season.
He said: "It's complicated because it's the first time I've stopped training for 35 years. But two or three months of rest must be good for the body.
"I will do it again, soon.
"Germany? I do not think so. The problem with international work is that I need my drug to train every weekend. When you've known that, you cannot live without it."
