Far from content to hide in their shadows, however, the 24-year-old has laid down his challenge to whichever of the pair he meets in the last four.
"Obviously the Grand Slams are the tournaments that we want to win the most. Before, maybe the last few years, I was putting too much pressure on myself," Zverev said, following his 6-4, 6-1, 6-1 victory. "Also obviously in the media I was seen, before Medvedev and Tsitsipas arrived, I was seen as this guy that was going to all of a sudden take over the tennis world...
"I was not very patient with myself, which I feel like now maybe I learned how to deal with the situation a little bit better, I'm maybe a little bit calmer at the tournaments. But the end goal hasn't changed."
In a scrappy first set, which included seven breaks of serve, the sixth seed snuck it to seal the advantage over the 22-year-old, who had never advanced this far on such a stage.
