Shkodran Mustafi is not exactly a 'fan favourite' at Arsenal.
The 26-year-old German defender moved to north London from Valencia for £35m in 2016.
But Mustafi has struggled in the Premier League and his two-year spell under Arsene Wenger was littered with calamitous mistakes.
The veteran French manager was replaced by Unai Emery this summer.
Formerly at PSG and Sevilla, Emery undoubtedly has a very different coaching style to his predecessor.
Mustafi was in the starting XI for Sunday's 2-0 defeat to Manchester City and admitted that he's enjoying getting some tactical instructions from his new manager.
“He [Emery] told me the positives in my game and what to work on," said Mustafi to the Evening Standard.
"I’m happy because it’s difficult when you never know what to work on because no one tells you."
Plenty of Arsenal fans were appalled at Mustafi's comment, which appeared to be a dig at the club's former manager.
Perhaps Mustafi didn't intend to fire shots at Wenger but the damage has already been done - Arsenal supporters on Twitter were not happy.
One fan posted a video of Mustafi's horrendous error in the League Cup final last season, asking him what Wenger could've done about it.
Mustafi is expected to start when Arsenal visit Chelsea in the Premier League on Saturday evening.
He's probably better off doing his talking on the pitch.
Despite defeat in his first game as Arsenal manager, Emery is refusing to panic.
“The first game gives us more information about things to improve and also things to continue doing,” Emery told reporters.
“It’s clear that the result was the first [objective] we wanted. But it was Manchester City’s day.
“We need to continue with our work to make the differences in the next match and in the future.
“We want to build a competitive team. We are going to play away but we need to keep our personality, keep our mentality, because I think on Sunday against Manchester City, the team kept their ideas, kept their spirit in the game for the full 90 minutes, even when we were losing, and didn’t let [their heads] go down."
