Zverev is in the same group as tsitsipas, rublev, rune, shapo, etc. In that they are temperamental, spoilt and ugle attitude asf when they came.on the tour. Some, e.g rune, shapo, tsitsipas seem to be maturing out of it. Carlos tends to ride the positive wave until he starts to overhit and make errors when he doesn't need to. Also prone to outbursts of frustration from time to time when down on form. Hope he comes out of it, esp against players like sinner, who seem to be consistent throughout. Otherwise the rivalry will be anything but.
