Per Mertesacker has addressed his on-field berating of Mesut Ozil after Arsenal's 6-3 defeat to Manchester City earlier this season - and for Arsenal fans, it makes for interesting reading.
Speaking to the Guardian in an interview that covered a number of topics, the Germany defender said he thought that kind of passion is disappearing from the modern game - at least in public.
The Arsenal centre-back screamed at Ozil after his Gunners teammate appeared to be heading straight down the tunnel following the heavy humbling at the hands of Manuel Pellegrini's side.
Arsenal, like many teams, make a point of saluting their travelling fans after every match - something Mertesacker wanted to make clear to the new Gunners recruit.
"We have to present ourselves as a unit, not matter what happens," he told the Guardian. "That is what Arsenal stands for.
"He was just angry, so was I and, sometimes, it's good to argue, to let your feelings out. It's nearly disappeared in football life because when something happens, players keep it inside and they are pissed off over the next three weeks.
"That's not what I want to see with anybody. There can be a little battle, but, afterwards, shake hands and forget about it. That is a culture I like."
Ozil apologised to the Arsenal fans shortly after the episode, and he's enjoyed a largely successful first half a season in English football.
The Gunners are well and truly in the title race, a turn of events that not many predicted at the start of the season.
They face Liverpool at Anfield this weekend, but the Premier League fixture list only gets more difficult for Wenger's side in March as they face Chelsea, Manchester City and Everton.
