Lucho didn't impose on his will on anyone worth anything at Barca.
He tried that shit with Totti first, had to eat humble pie and repaired that relationship in the end but left anyway after one season. Then tried it again with Messi and was almost sent packing lol.
Even the tactical change to move Suarez from the RW to ST was something Messi did for him as he insisted on playing Suarez out wide.
I don't know how his relationship with Mbappe was in Paris.
Point is....he's a disciplinarian for sure, but when he's tried it with the bigger players he's fallen flat on his face more often than not. Even Pep knew he had to treat players differently even if he held everyone to the same standard. Lucho trying to act like a hardman with everyone isn't smart.
He didn't eat any 'humble pie' what are you on?
His switch of Suarez to ST was all due to him, not to Messi who had been accustomed to the false 9 role and didn't wanna change
He made it clear since day 1 'I am the leader of this team' and that did not seat well with the primadonas that had already started since 2011 2012 or so to feel bigger than what they really were
When Messi tried to test his limits he saw the bench, like everyone else in Lucho's career.
Xavi intervened to repair the relation, and not as you imply
In the end the repair worked for everyone, but it was clear who has the upper hand...
Messi managed to had it his way only with his yesman Tata, and after that with Valverde
