(BBC) Andy Murray wants to appoint a new coach before the clay-court season with a possible decision in the next couple of days, BBC Sport understands.
Murray is enduring the worst run of his professional career – four successive defeats in straight sets.
He accepts he needs a new coach with experience, as long as he can find the right person.
Ideally he wants to appoint someone for 20 to 25 weeks a year and wants them in place as soon as possible.
His schedule is hectic from mid-April through to the end of Wimbledon in July and he does not want the issue to preoccupy him more than it already has.
On Tuesday he parted company with part-time consultant Alex Corretja after three years.
Corretja had previously worked in tandem with Miles Maclagan who was sacked last summer.
During the early part of his professional career Murray was coached by Mark Petchey and then Brad Gilbert.
Meanwhile Murray, who has remained at his base here in Miami following his defeat to Alex Bogomolov at the Sony Ericsson Open, has started his clay-court preparation.
He has found some green clay courts at a local club close to his apartment and has been practising with hitting partner Dani Vallverdu and physical trainer Jez Green.
He is considering a wild card offer into the Monte Carlo tournament which starts a week on Monday.
