sometimes he really gives the impression he's in a spiral of negativity, and I even thought it was his main problem personally
He is negative sometimes, but most of the time it's only after bad errors. Like I said, his "negativity" isn't the reason he loses matches.
You made mistake, I helped you.
Wrong. Haas is not a legend. His style of play is rather nice to watch, but he's an idiot, if even only because he called Murray a faker. Murray doesn't fake, ever. Only an idiot would say so.
Murray is negative on court because he knows he relies on opponents failing to win matches. So whenever an opponent hits winners or consistently good shots, he knows he's toast.
That's why he has over 370 match wins. Because he was toast in most of them, right?
You talk utter rubbish, nothing has changed.
