It's safe to say Barcelona full-back Aleix Vidal is not a happy bunny at the moment.
Vidal has dropped down Luis Enrique's pecking order this season, despite Dani Alves departing in the summer and his future at the club has been plunged even further in doubt after his latest activity on social media.
Five games into the La Liga campaign, Enrique has preferred to use Sergi Roberto and even Brazilian Rafinha on the right of Barca's defence over the more accomplished Vidal.
And fresh speculation this week linking Barcelona with a move for Arsenal defender Hector Bellerin suggests Vidal is not seen as the long-term - never mind short-term - solution by Enrique.
The right-back was snubbed from the matchday squad once again for Wednesday night's 1-1 draw with Atletico Madrid at the Camp Nou.
He appears to have taken exception to the latest jibe from his manager by releasing a controversial Instagram post.
Vidal's account has over 732,000 followers but it is actually private so cannot be accessed by everyone.
Unfortunately for him, however, one of those who can see what he puts is Marca journalist David Sanchez, who has leaked his latest post to the rest of the world.
As you can see by the tweet below, Vidal does not directly reference Barcelona or Enrique specifically, but fans have put two and two together from his combination of emojis used in the accompanying caption.
One is the face with a zipped up mouth next to the finger symbol for 'f*** you'
At this stage, it is still important to stress that Vidal may not be referring to his employers, nevertheless, it doesn't look good.
The attention will now turn back to Enrique to see if he responds with some form of punishment, providing proof who the post was directed at is actually discovered.
