Grigor Dimitrov has split with his coaches from Magnus Norman's Good to Great Academy in Sweden, but hasn't decided if and when he will hire another coach, TENNIS.com has learned.

Norman said in a statement that their relationship had ended because Dimitrov was spending more time training in Los Angeles than in Stockholm. Dimitrov's girlfriend, Maria Sharapova, owns a home in L.A. and often trains there.

The 29th-ranked Dimitrov signed in his father Dimitar as his coach at the tournament in Beijing. His father is a teaching pro and taught him how to play.
