Ditch the chick & get Lendl back

Ditch the chick and get Lendl on the blower and convince him to come back.
That would be my advice to Andy Murray
Murray before and after Lendl = useless in slams
Boris Becker speaking on the role of 'supercoach:
“I think it was time for the top players to understand that if they want to improve and get a bit more knowledge – and it’s the same in any business – then they need to go to the established ones, the veterans who have done it before for many, many years."
Mauresmo maybe an expert of the woman's game but is no expert regarding the men's tennis circuit.
