He further shared the consequences if the Minsk, Belarus, native loses the match."Pressure will be big. There is more on the line than just a Grand Slam title. For Aryna (Sabalenka), it's a very, very important match because she's lost in the final of the Australian Open against Madison Keys. She lost in the final of Roland Garros against Coco (Gauff)."He continued,"But mentally, the way she processed during the final cost her the final two times. So it's a great occasion for her to break that problem and sort it out. If she does, I think it's going to help her tremendously in the next seasons and probably she will be able to win many more majors. If the same scenario happens again, it's going to hurt her really bad."
