Navrátilová: Berdych needs tougher coach

The leading Czech men’s tennis player Tomáš Berdych needs a tougher coach, says Martina Navrátilová. The Czech-born legend, who was world number one for seven years, told Czech Radio that Berdych was talented but could be higher up the world rankings than his current fifth place. The winner of 18 Grand Slams, Navrátilová said jokingly that she had more advice for the 29-year-old but would need to be paid to share it.
