I think it's more his injury record than his body language or age to be honest.I am still amazed after 3 years of watching Aina people still think he is knackered after one sprint. It's his body language! He looks knackered after 10 minutes in a match.
He is also 29, not 35.
He just doesn't seem to be very robust, a wing-back generally is probably the most physically demanding position to play and that's even more so in a high-intensity system like Glasner's. I'd be surprised if Aina managed more than 5 consecutive games playing before his bones crumble into tiny pieces.
