Messi is not leaving Barcelona after staying here for nearly 20 years just because they decided to get rid of Suarez. He had already made his decision to leave before Barto opened his mouth to a select few journalists that are in his camp. Heck it was reported by people close to his family that warned that he might be leaving this summer, this was reported in January 2020.
People might believe that and they are free to do that, but there's been talk about him possibly leaving for two years now. He negotiated hard and long for this clause to be included for a reason. Perhaps to keep the pressure on Bartomeu and the board to build a winning project which they have failed to do. Not to forget hiring a company to slander him and the players on social media, Mundo Deportivo and Sport constantly blaming the players and Messi for doing XYZ and wantng XYZ player while never questioning Bartomeu's management.
Even after the Bayern loss you have these two media outlets claiming it's a sporting crisis and not an institutional one, once again blaming the players and Messi in particular and not even lifting a finger to question Bartomeu and this board for how we even got to this point and mess in the first place.
