Andy Murray is prepared to appoint another former star player as his coach after splitting with Amelie Mauresmo.
Murray decided to part company with the ex-world number one before his run to the Madrid Masters final, citing a lack of time together as a chief concern.
Prior to Mauresmo, Murray, 28, worked with Ivan Lendl, who guided him to US Open, Wimbledon and Olympic success.
"It doesn't have to be, but it's definitely possible it could be an ex-player," the Briton told BBC Sport.
He said coaches who had played at the very top can "help around the Slams, in the big moments, the big matches".
