Luis Enrique had a fight with Messi and Neymar. Iniesta has said that he didn't always agree with Enrique's tactics. I think Jordi Alba and Enrique also had some issues in the last season.
I think Luis Enrique wasn't the most liked coach, but I do think he won the respect of the players. That is what is most important. Also he was praised for his training methods.
Don't remember the fight thing with Neymar, but I think the Messi thing was around the Anoeta game? although many said it was just a train clash and nothing more, Alba thing is true too tbf. Iniesta comments was before or after he left? And it isn't really my point, not agreeing with tactics is another thing
Pep had a problem with Eto,Hleb and Ibra that were on way larger scale than any of those. Rijkaard had same problem with Eto and other players, Tata lost the whole dressing room and even LVG if you decide to go this far back.
Agree with the last line, overall I don't think saying "he doesn' comminicate well with players" is fair argument by any mean
