As an interviewee, Murray has almost always been polite, patient and generous with his time - and very good value. I can count on one hand the number of times he turned me down for an interview, and one of those occasions was after the 2016 Australian Open final against Novak Djokovic. He went straight from the Rod Laver Arena to the airport to catch the last flight of the night, as wife Kim was at home, heavily pregnant with their first child.

Murray is often shivering when I interview him - a recent plunge in the ice bath tends to do that to you. But it shows character to do a (non-mandatory) radio interview after a Grand Slam final or semi-final defeat, of which Murray suffered a few.

As with all marquee names, there was sometimes tension in the air as the post-match media round approached - especially, I remember, at Melbourne Park following one of his frequent semi-final victories. Commitments would be honoured in the early hours of the morning, but everyone was very conscious of the clock ticking down to the Sunday final.

Murray is invariably good copy, as we like to say. He has been steadfast in his criticism of those who break doping rules and in his support for equal pay and female coaches - once describing the level of sexism in sport as unreal.

His strong opinions are, though, expressed diplomatically. And on occasions, when time allowed and microphones were off, he was happy to expand on his thoughts in confidence.

There were differences of opinion - and the odd falling out - with the British tennis media. Following his late withdrawal and subsequent hasty exit from the 2018 Brisbane International, Murray was unhappy about some of what was written in the absence of any formal explanation.

A slightly surreal off-the-record, clear-the-air session followed on speaker phone a week or so later - but only after he had briefed us from his Melbourne hospital bed about the hip operation he had undergone earlier that day.
