Mesut Ozil's cryptic social media post has not only got Arsenal supporters talking, but some of his current and former teammates too.
On the eve of the Gunners' Europa League tie against Vitoria, the 31-year-old posted an image of himself laughing during a training session with a message which reads: "You make me laugh."
It's not clear as to who Ozil was directing this message at.
However, the popular theory among some supporters is that the playmaker was aiming a dig at head coach Unai Emery following an interesting exchange between the pair earlier in the day.
And judging by the reaction on Instagram, it would appear that a few of his teammates are on his side.
As pointed out on Twitter, Pierre-Emerick Aubameyang, Alexandre Lacazette, Granit Xhaka, Shkodran Mustafi, Ainsley Maitland-Niles, Sead Kolasniac, James Olayinka and Rob Holding all 'liked' the post.
Even Santi Cazorla - a former Arsenal player - and Mohamed Elneny who is on loan at Besiktas this season 'liked' the post.
Of course this all could mean nothing.
Or could this all be connected with Ozil's relationship with the Gunners' head coach?
Tonight could mark Ozil's return to an Arsenal matchday squad for the first time in a month.
The last time he featured was in the 5-0 win over Nottingham Forest in the Carabao Cup, although he didn't see out the full 90 minutes as he was replaced midway through the second half.
As a result, all eyes will be on if Ozil arrives at the Emirates Stadium as part of the matchday squad or as a spectator.
