Tony Adams and Arsene Wenger aren't exactly on the best of terms right now.
The former England international spent his entire playing career at Arsenal and was an integral part of Wenger's team during the late 1990's/early 2000's.
Any yet it is safe to say the pair have struggled to maintain their seemingly solid manager-captain relationship since Adams retired in 2002.
Wenger, who is already under pressure to turn things around at the Emirates following a difficult start to the campaign, has received a spate of criticism from Adams over the last few months.
The Arsenal boss opted to extend his tenure at the club for another two years in the summer despite missing out on Champions League for the first time in his reign.
In a fresh attack on Wenger, Adams has slammed his old manager's ability to improve players and claims he missed the best opportunity to walk away from the club after beating Chelsea in the FA Cup final.
"For preparation and recovery he was better than anyone. As a psychologist - regarding his interaction with his group of players - he was fantastic, second to none," the 50-year-old told the Islington Gazette.
"But did he teach me anything? No. Did he teach me how to defend? No. He didn't teach Nigel [Winterburn], Dicko [Lee Dixon], he didn't teach Bouldy [Steve Bould] or Dave Seaman.
"Arsene should have gone in May. He will have a place at Arsenal forever but my personal opinion is that he should have gone after beating Chelsea. It's going to end in tears."
There's no love lost there then. Adams' revelations certainly won't make any of Wenger's critics feel any better about his current predicament.
The Frenchman will be hoping to prove Adams wrong when the Gunners return to action on Saturday as Bournemouth visit the Emirates Stadium.
Alexis Sanchez could feature for the first time since his deadline day move to Manchester City collapsed, meanwhile Alex Oxlade-Chamberlain's departure will force the Arsenal manager into at least one change from the starting XI who lost 4-0 to Liverpool at Anfield.
