Messi will not go anywhere.
This time, I agree with. 
Messi seems not really serious to leave Barcelona. Maybe it is only a rumor that he wants to go Man City. Moreover, he is not a typical player who wants a new challenge in his career. He is not the same as CR7, Ibra, or other players who try playing on other teams before they retired as professional football players.
In Barcelona he is the best king.
What do you mean?Are you trying to tell us that Messi is the king of Barcelona?
So, even Barcelona has a president club, Messi can decide everything he wants because he is the king, right?
Wow, I am a bit surprised by this fact.
