After their late victory over Everton, Liverpool centre-back Dejan Lovren was in a celebratory mood.
The Croatian international shared a photo of himself and his Reds teammates after Sadio Mané's stoppage-time goal settled the Premier League game at Goodison Park.
But more eagle-eyed observers spotted something else in the Instagram post. Can you work out what it is?

If you were still looking at the photo itself in the hope of some kind of magic eye trick, let us stop you now.
The talking point is the conversation below between Lovren and José Fonte, former teammates at Southampton.
Now, in situations like this there is always a perfectly logical explanation.

But there's also another, more obvious interpretation - in the view of some people, at least.

Liverpool haven't been the most solid at the back this season, particularly when Joël Matip hasn't been involved, and Fonte has been linked with a move away from St Mary's.
The Euro 2016 winner could be a good influence on a team which is challenging for the Premier League title despite conceding more goals than 14th-placed Middlesbrough.
Alternatively, though...

Of course, there's always a spoilsport or two to point out the other option, which inevitably works out as being even more obvious than options one and two.

Hopefully both Lovren and Fonte will leave us all guessing.
