This is just made up nonsense.
Sané was a cracking player who had pace, two feet, good skill, good passing, good shooting from close and distance, can play both right and left (and now also in the middle), and was a constant goal threat either with assists or goals.
Sané was rarely lazy (you catagorically do not achieve 100 points as a team if you have lazy players, it just would it happen whatsoever!) , and was only petulant on two occasions that I can remember in his entire time with us (both were justified n’all) and most attacking players are inconsistent. de Bruyne has stunk the place out with some of his poor performances over the last few years but his inconsistencies also mean who can be the best player on the pitch.
