This does not bode well for Tiafoe, he hired a real coach in Wayne Ferreira yet the results are the same, very ordinary. Shame because Tiafoe showed so much potential 3 years ago with Ginepri. He got rid of Ginepri and was "coached" by his buddy for two years and stagnated. Musetti is the real deal though. Imagine what Musetti will be doing in 2-3 years when he has ATP experience.
