Yep. Noticed that too, he's a lot stronger but seems to have lost a couple yards of pace. It's made him a better dribbler, funnily enough.
Most impressive improvement though is in his first touch. Earlier this season it looked erratic, like it was in Italy. Yesterday was back to last season's level. When he's in this form he's unplayable
Btw, about the suarez comparison: suarez is the third best player of the last decade. It's not even close. At times, he's been genuinely as good as Messi/Cristiano. Check out his 15/16 season for barcelona...
