So you are saying that AM has a mindset that is stupid and delusional? He's a little bit lost right now but think saying he is a fantasist and both delusional and stupid is a bit strange!!
He says he needs to win more matches to push his ranking back up, then immediately says his main goal is to win Slams. He isn't going to win Slams without winning matches, and right now he's not doing that, and that is due to him not giving a toss about small events and this new habit of handing sets back to those who deserve to lose them.
