Former British journeyman player Maclagan is said to have indicated that he was no longer happy working as part of a two-man coaching operation. He has been sharing the work of overseeing Murray's training with part-time consultant Alex Corretja. Although the British No 1 tried to persuade Maclagan to stay on in the present arrangement, the coach wanted to be in sole charge, as had been the case throughout the grass-court season.When the 23-year-old Scot made it clear he still wanted that wider range of input, the men decided to part ways. The split may explain why Murray decided to cut short his training camp in Florida, which Maclagan had attended, for a last-minute entry into the Los Angeles Open, where he plays his opening match on Wednesday.
