Former Arsenal Invincible Jens Lehman has posted a cryptic message on social media after new Gunners boss Unai Emery announced his coaching staff – with the former German international goalkeeper not included.

The revolution at the North London giants has gathered pace after the new head coach confirmed his off-field line-up following Arsene Wenger’s departure after 22 years in charge of the club.

While the long-serving Frenchman’s No2, Steve Bould, has been retained by Emery, Lehman has been released.

The former netminder, who was part of the memorable 2003-04 side, tweeted his thoughts after being let go – leaving many Arsenal fans confused as to what he meant.

He posted on his personal Twitter account on TUe4sday afternoon: “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.”

Emery’s backroom staff will feature Juan Carlos Carcedo as first team assistant head coach, while the first team assistant head coach will be Steve Bould – who has been retained after working as former manager Arsene Wenger’s No2.

First team coach will be Pablo Villanueva with director of high performance being Darren Burgess.

Emery’s backroom staff at the Gunners for the 2018-19 season also includes Julen Masach as strength and conditioning coach while goalkeeping coaches will be Javi Garcia and Sal Bibbo while the club’s data/video analyst will be Victor Manas.

Arsenal chief executive Ivan Gazidis said: “Unai has a very strong and talented team and I’m delighted that they are joining us.”
