Many Chelsea fans were left fuming at manager Enzo Maresca after Arsenal defender Jurrien Timber appeared to 'embarrass' him with a blunt two-word message during Sunday's 1-0 defeat at the Emirates.
The match, decided by a 20th-minute header from Mikel Merino from a Martin Odegaard corner, marked another frustrating outing for the Blues, who have now lost four consecutive away games in the Premier League.
Maresca's side also extended their winless run against Arsenal to seven matches.
But while Chelsea's on-field struggles will be the primary concern for most Blues supporters, some fans on social media appeared more triggered by a brief touchline exchange between Maresca and Timber.
