Britain's Emma Raducanu believes her current coaching arrangement is working well but knows she will soon need to "figure another solution out".
The 22-year-old still has a desire to develop a longer-term partnership with Mark Petchey, even if the pair were unable to agree a more exclusive arrangement.
But Jane O'Donoghue, a friend and former Lawn Tennis Association national women's coach who is alongside Petchey at this week's Italian Open, is only on a sabbatical from her current full-time job in finance.
"It's been working pretty well," Raducanu told BBC Sport in Rome.
