The midfielder's typically jovial personality was replaced by a firmer one and he called for improvements in his team's mentality
Jorginho has called on his Chelsea team-mates to rediscover their aggression after overcoming a poor first half to win 2-1 away at Arsenal and tailing off an inconsistent December run.
Frank Lampard's side struggled as they went 1-0 down to Pierre-Emerick Aubameyang's header at the Emirates Stadium, but ultimately turned the game around to defeat their London rivals.
Blues' vice-captain Jorginho was brought on in a desperate 34th-minute substitution, with the west Londoners having been under intense pressure early on in the match.
