But this time La Liga will be very competitive. Atletico Madrid is very good team in this time.
Sorry, but I don't think this season is the best time for Atletico Madrid. They started this season with unsatisfied results. Look at the table, he played 3 times, win 1 time only and draw 2 times. Consequently, they dropped to 12th place. In my opinion, a club that Barcelona must watch out is Real Madrid.
I don't think Messi is interested in staying Barcelona anymore.
Who knows! How if Barcelona management offers him to be an assistant coach if he stayed. Then, he has a chance to be a Barcelona coach in the future. I think it is very possible and hard to refuse.
I think his goal is to win the World Cup for Argentina. (it is my personal opinion, don't think that Messi said that on media)
All people know about this. Of course, he is very ambitious to have the World Cup trophy. It is easy to say since he never wins it, and he probably needs it to complete his career in football. Surely, we don't need to prove it with his statement on media. We all know he wants it.
