Arsenal's new manager Unai Emery is beginning to ring the changes in north London.
On Tuesday afternoon, Arsenal confirmed that first team coaches Neil Banfield, Tony Colbert, Jens Lehmann, Gerry Peyton and Boro Primorac had left the club.
“All these people have played a huge part in the club’s success and development over many years," said Arsenal Chief Executive Ivan Gazidis, as per the club's website.
"We thank them for all their hard work and wish them all the best for the future.”
The news seemingly didn't go down very well with the former German goalkeeper.
Lehmann spent five years as a 'keeper at Arsenal and was a key member of the famous 'Invincibles' team of 2003/04.
Former manager Arsene Wenger hired him in July 2017 as a first-team coach.
Lehmann's tweet causes a stir
Lehmann, 48, posted a tweet minutes after Arsenal confirmed that he had left the club.
The meaning of his final sentence could be construed in different ways but the majority of fans on Twitter appeared to think the enigmatic German was firing shots at Arsenal.
He tweeted: "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."
Geoff Shreeves - and plenty of Arsenal fans - believe Lehmann wasn't taking Emery's decision very well with his social media post.
Petr Cech had a poor season and German goalkeeper Bernd Leno is expected to join Arsenal from Bayer Leverkusen for £19.2m.
Goalkeeping coach Gerry Peyton was also sacked by Emery on Tuesday, with Javi Garcia and Sal Bibbo confirmed as the goalkeeping coaches for the season ahead.
Meanwhile, Steve Bould will continue as Arsenal's assistant head coach under Arsene Wenger's successor.
Juan Carlos Carcedo will be alongside Emery in the dugout having spent the last 12 years working as the Spaniard's assistant.
Arsenal's Premier League season commences in August with tricky fixtures against Manchester City and Chelsea.
“The target is to be a candidate and to challenge for the title," said Emery at his unveiling last month.
"It is very important for the club, after two years outside the Champions League, to work this way, to be the best club, the best team in the Premier League and also in the world.”
