"The tense meeting between Messi and Sampaoli" on the header, then you keep reading and see that it wasn't just Messi, it was Messi and Mascherano, voicing the concerns of the whole team "Lionel Messi and Javier Mascherano called a meeting with Jorge Sampaoli and the rest of his staff.".
"The purpose of the meeting was clear, to make him see that the squad no longer trusted him. 'We don't get what you say, we don't trust you anymore and we want to have an opinion,' was their argument."
Now, the part where Messi actually comes into play. "Messi took to the floor and was also unhappy with Sampaoli asking him who he should bring on,
a moment which was picked up by cameras.'
You asked me 10 times which players you wanted me to see on and which ones I didn't and I never gave you a name,' he said."
"The meeting calmed down after a lively start but things never boiled over"
