I'd agree with that, but I don't think that's down to injury. I think he is conserving his energy in a lot of matches and playing in bursts. He's certainly inactive, playing at walking pace for stretches of games. Whether that's necessity or just the reality that there are games that are going to need him more that PSG I don't know. He's been to Italy this week talking to a nutritionist apparently - maybe that's related.
But in terms of what he's doing in those bursts he looks impressive to me. There aren't many games where he needs to pop up more than two or three times and Enrique seems to have arranged it so that it doesn't matter. Anyway he's looking handy again today
