He looks fine. People in this forum are always overreacting to photos of players' stomachs. Messi, Suarez, Arda, Alba, etc. When you're discussing whether a player's in good shape, the main thing you're interested in is fat percentage, and you can't calculate that based on a photo. And you most certainly can't figure out whether a player has gained some fat based on comparing different photos (if we're talking about a few % up or down, and not extreme fat gain/loss).
The way a stomach looks in a photo depends on whether the person was breathing in or out at that moment, what they've eaten last, how long it's been since their last meal, how much water they've had to drink, how long it's been since their last drink etc. etc. etc..... and among a billion other things, fat percentage. A protruded stomach means nothing. A stomach with fat hanging off it means something.
If a person with absolutely perfect abs and no fat on their abdomen drinks a whole bottle of water, they're gonna have a
belly.
Here's a gif to put things into perspective.
