Former Arsenal goalkeeper Jens Lehmann is back at the club after he agreed to join Arsene Wenger's coaching team.
The 47-year-old won one Premier League title and one FA Cup during his spell at the club.
He has already made his return to London Colney.
Mirror has claimed that the former goalkeeper will take "a more general position in Wenger's team".
Towards the end of last season, the German defended manager Arsene Wenger who was heavily criticised by some Arsenal fans.
"The players should have tried to hit that plane with the ball, to defend their manager," he said in March.
"A single guy comes and holds a banner up, that's his opinion, fine.
"But hiring a plane? Come on, it's too much.
"Even now the guys who are against Arsene they should recognise it has gone too far.
"Bring Allegri in and we will win everything? Who is Allegri, with all due respect? He is in Italy. Will somebody like him bring success?
"When you look at the type of football he is playing, it doesn't really fit Arsenal.
"None of them has a solution, someone who would guarantee them Champions League football and maybe win something."
