In and out of the first team, Arsenal wing-back Sead Kolasinac has failed to fully convince Arsene Wenger since joining in the summer.
Sky Sports pundit Gary Neville made his thoughts clear on the 24-year-old Bosnian international during Thursday night's 3-0 defeat to Manchester City.
Pep Guardiola's treble-chasers ran riot against Arsenal's substandard defence for the second time in four days.
The Arsenal backline was brilliantly cut open by some scintillating attacking football and goals from Bernardo Silva, David Silva and Leroy Sane put the game to bed within 35 minutes.
"This is an amazing team," said Arsenal legend Thierry Henry on Sky Sports. "When you look at the movement and creativity. They are team goals. Those goals that you try to create in training.
"They make you enjoy football. Joking apart, this is what you want to see."
Arsenal fans have not been enjoying football very much recently and boos rang out in a half-empty Emirates Stadium on Thursday night.
There were plenty of dismal performances on show but Kolasinac was singled out by Neville for some brutal criticism.
Neville drops truth bomb on Kolasinac
Gary Neville was on TV commentating duties once again and the former Manchester United defender called out Kolasinac late in the first half.
"Kolasinac needs help," said Neville on Sky Sports.
"The problem with Kolasinac is that he can't move his feet.
"Manchester City, every one of their players can. So when they change the direction or a quick combination around him, he's struggling badly."
It's brutal but Neville hit the nail on the head.
Signed on a free transfer from the Bundesliga, Kolasinac looked brilliant in the early stages of the 2017/18 campaign - but he's lost the 'fan favourite' tag in north London almost as quickly as he earned it.
The Gunners now find themselves ten points off fourth placed Tottenham and the situation appears to finally be reaching breaking point under Wenger.
