He was in the press this year saying he wants to stay.
If he was telling Barto all year he wants to go then also goes against the idea he did not want to activate clause by tenth June as would disrupt season.
Messi could have told them by 10th he wanted to go and still change his mind or he could have asked for an extension to clause.
Came across in that interview as telling his own version of events that doesnt seem realistic.
This whole argument about the 10th is unconvincing and kind of presumptuous.
Again, people like to fantasize about meticulously calculated actions on the motives of rational agents , whereas in fact people act very differently from rational robots.
What if Messi tells the simple truth that Barcelona was in all competitions and he wanted to conclude the season, thinking probably (mistakenly of course) that a CL can be won?
What if he did not even know that the clause specifies a date by which he should inform the board and had always in his mind 'the end of the season'?
About telling Barto the whole season that he will be gone, none of us knows what was said exactly behind closed doors.
It does not look unlikely to me that Messi could have said to Barto a couple of times that he sees it difficult staying for another season, and Barto as a cunning devious prick that he is reassured him that he has the freedom to decide when the season ends, knowing full well himself that he can manipulate Messi around the formal legalities of the contract.
