Raducanu simply doesn’t have the physical or mental attributes required to be an elite professional tennis player.
Since she won the US Open, I have consistently thought that she had the makings of a top player, and that it would only be a matter of time for it to all click, but the reality is that her victory was a complete fluke. I don’t know whether her body cannot cope with the exertion of tennis, or whether she has an unusually weak pain threshold, but the number of times she has pulled out of matches in the past few years is crazy.
