Andrew Burton on Djokovic's record weeks at number 1 and return of Federer

Andrew Burton joins Matt Zemek to talk about the state of both tours through the lens of Big 7 - the four majors, ATP, WTA and the ITF. The duo also touches upon the return of Roger Federer to tour after more than a year of absence. The conversation shifts to Novak Djokovic's world record for most weeks at number one. Danil Medvedev's ascent to world number two gets a mention as he is the first non big 4 player to rank this high.
