A superstar tennis player has the desire to win at all cost and the tennis talent to do it - in that order! Coaches probably can guide but cannot produce a top player; but it is the player who either wants it badly to commit all energies to that task.
Every great player had a superb coach. The Williams' sisters had Rick Macci. Agassi was around a wealth of tennis knowledge his entire life: remember Segura tried to do what Gilbert eventually accomplished. Talent without training and knowledge is useless.
