Thanasi Kokkinakis takes on fellow #NextGen star Daniil Medvedev on centre court at the Aegon Championships today, and part of his pre-match preparation was to join Catherine Whitaker (Eurosport) and Gigi Salmon (BBC 5 Live) on the Tennis Podcast.How many text messages did he receive after his stunning win over Milos Raonic in the previous round? How stressful was it trying to close out a match of that magnitude after so long out? And most importantly, what superpower would he choose - invisibility, x-ray vision, or the ability to fly?Elsewhere, Tomas Berdych won the match of the tournament so far, edging out Denis Shapovalov, and Grigor Dimitrov overcame a set deficit against Julien Benneteau.
