Jens Lehmann has taken aim at Arsenal after being dumped from the club's backroom team.
Former Invincibles goalkeeper Lehmann is leaving as new manager Unai Emery brings in his own men.
Lehmann offered what seemed to be a thinly-veiled swipe at the current squad on Twitter, where he wrote:
"Dear Arsenal fans , I am sorry to leave the club after only one year again.
"It was a good experience working with the players as one of the assistant-coaches. But the attitude from our 2004-group is not needed there anymore."
