Andy Murray is testing out retired Swedish tennis player Jonas Bjorkman, with a view to adding the doubles specialist to his coaching team.
The fourth-ranked Murray has been looking for a second coach to work alongside Amelie Mauresmo since splitting from long-time team member Dani Vallverdu in November.
Bjorkman will spend a week with Murray next month ahead of potentially joining the player's coaching team on a permanent basis.
Murray said last week that his poor recent performances in tournaments in Rotterdam and Dubai, where he was eliminated in the quarterfinals, were down to Mauresmo being occupied with Fed Cup coaching duties with France.
The 42-year-old Bjorkman retired in 2008 after winning nine Grand Slam doubles titles and reaching a career-high singles ranking of No. 4.
