Granit Xhaka's captaincy at Arsenal has been thrown into doubt following Sunday's 2-2 draw with Crystal Palace.
Xhaka's substitution was greeted with cheers from the Emirates Stadium crowd, sparking a furious response from the midfielder.
The 27-year-old told Gunners' supporters to "f*** off" as he left the pitch before removing his shirt and heading straight down the tunnel.
Arsenal boss Unai Emery insists he will talk to Xhaka before deciding whether to strip him of the Arsenal captaincy.
"He was wrong, he was wrong," Emery admitted. "Now we need to stay calm and speak with him, to speak inside about that reaction. His reaction was wrong in that moment."
The Arsenal man is one of 68 midfielders to have featured in at least nine Premier League matches so far this season, and is therefore viewed as a key component in his side's system.
Despite this, Xhaka has often been a target for the Gunners faithful - but is their criticism fair?
Tom Carnduff looks at the statistics behind his performances so far and compares the numbers with the other regular starters in England's top-flight.
Passing
Xhaka missed Arsenal's convincing 5-0 victory over Nottingham Forest in the last round, so it wouldn't be a huge surprise if he wasn't involved again when they face Liverpool in the EFL Cup.
A lot will be made of the incident and the impact that has had on Emery's team selection, but he did opt for Lucas Torreira and Joe Willock in the deeper midfield positions during that victory.
A lack of involvement for Xhaka could be a good look for Emery and Arsenal, even if he wasn't planning on playing him against Liverpool.
The immediate response will be one of discipline as opposed to tactical reasons. It'll strengthen Emery's hand when it comes to dealing with incidents within his squad, and given the ongoing struggle with Mesut Ozil, it's needed.
A lot depends on what emerges from Emery's meeting with Xhaka this week. He's been a regular part of this Arsenal side and clearly a favourable player in the manager's thinking, so if it is resolved then there's a strong chance of involvement against Wolves.
On the flip side, there is a school of thought which says there is often no coming back from this. For a player to be jeered by their own fans is bad enough, let alone that player being the captain, and his response only poured fuel on the fire.
If the issue won't go away then a quick sale in January may be the answer to maintain squad harmony. There would be no shortage of offers from clubs around Europe for his services, whatever the stats above may suggest.
