Haha, it must be because of this photo, but indeed, it is a fact that Pogba was on the field and wearing the jersey, I checked his post on Instagram @paulpogba and indeed there are photos and videos of training with special guests.

However, the caption seems to just show a fishing rod that is out of the ordinary and makes a scene, and who knows what the real purpose is, but the post is indeed sensational. It's just that, there is no clear discussion about whether he is going to Real Madrid or not, because the caption is quite general.
