I don't think it's any exaggeration to say that Andy Murray was one of the favourites at the Australian Open before crashing out in the first round.
If you take away Roger Federer, Andy was in that next pack of four or five players.
Everyone fancied him to do well, they expected him to get into the quarter-finals or even possibly the semis and go on from there.
Murray was a surprise loser in Melbourne, beaten in four sets
He was unfortunate to come up against a dangerous opponent in Jo-Wilfried Tsonga who produced probably the most controlled match he's ever played in his career.
He caught Andy on what was, for him, a bad day. Andy should still have won, but did not play particularly well.
The expectation surrounding Andy was great. He understood that and knows about the media now, and his opponent was a tough guy to play against.
Tsonga is such a shotmaker, but can make a lot of errors and it means it can be difficult to get the tactics right against him.
Andy was a little bit guilty during the first couple of sets of waiting for errors which never materialised.
When he finally got his teeth into the match and started to play it was a little bit too late.
Andy's game centres on him being a strong counter-puncher. His main thing is to get through players, force them to come at him and then defend well and attack when he needs to.
Andy's second serve was vulnerable and by contrast Tsonga served extremely well to him
This time his game just was not there, and he did not adjust quickly enough to what his opponent was doing - that's strange for someone like Andy.
He was hoping for Tsonga to miss and I was a bit surprised by that.
I do not believe his problems were caused by his split with his coach Brad Gilbert.
Andy is normally a very shrewd tactician.
He did adjust - there were odd bits in the last tie-break where it came good for him - but he left it too late and we also need to give credit to Tsonga.
Another factor was in the serve: Andy's second serve was vulnerable and by contrast Tsonga served extremely well to him, going wide, forcing errors and getting a lot of cheap points.
The next factor is where he goes in terms of preparing with us for the Davis Cup tie in Argentina.
I expected him to get another three matches under his belt and then come out to join us in Buenos Aires just before that starts on 8 February, but now there's a big gap.
I am going to let things settle down for a few days and then chat to him about what the best thing is to do.
I'll certainly put my two cents in and try to get him to come up to Chile beforehand for some practice with the rest of the team.
