Over the past several years, former WTA and ATP players have experienced a renaissance of sorts, returning to the game as coaches for some of today's stars. With their glory days long behind them, they have stepped in to offer their advice and guidance to the next generation of players.
In some cases, it can be hard to keep up with who's coaching who given the constant turnover we see from year to year. With former players like Sebastien Grosjean (Nick Kyrgios), Sergi Bruguera (Richard Gasquet), Mardy Fish (Taylor Fritz and Jared Donaldson) and Robby Ginepri (Francis Tiafoe) jumping on the coaching bandwagon, it has further added to the trend of seeing familiar faces in the players' box.
