Messi didn’t not turn up last year. He knows mbappe is the star man there and has completely evolved into the creator role he now plays. His last few seasons at Barcelona he was gradually dropping deeper and dictating and now that is his only role. He will get goals here and there but his main aim/purpose is setting neymar and mbappe up now. The class act that he is, he doesn’t make a fuss about it at all.
That will be the difference between him and Ronaldo in the end. One quietly went about his business with no fuss, made amazing players world class players and the other was an egotistical maniac only worried about personal records.
