Having being brushed aside at Wimbledon by the rampant Rafael Nadal it was important to relocate him to his true roots just like we used to with Greg Rusedski and Lennox Lewis.

To be fair that's harsh and I don't really mean it.

I actually enjoyed his matches and I think he will get stronger with time. His support was again fantastic even against the mighty Nadal who looks to be a very worthy opponent for defending champion Roger Federer this year.

I said a couple of weeks ago though that if the last eight was where he was happy to finish, then that would be where he finished – and unsurprisingly, he did.

Interestingly, in the interview afterwards, Murray confessed to feeling as though he had not played his best and that he was completely outclassed by his opponent.

Again I have to suggest that this was due to his own last-eight, pre-tournament, prediction and because he believed that prediction, that was as far as he was ever going to go.

The power of belief is immense in sport. In fact the beliefs of a sporty individual I know were almost as affected as Murray's this week, due to another dose of Wimbledon mis-direction.

This particular person rushed home to see Murray in action and in doing so caught the back end of a Federer versus Mario Ancic match.

Having seen that Federer was two sets down and losing the final set 4-1 he decided – already logged on the net and out of interest – to see what the live bet odds where for Federer to make a miraculous comeback and in doing so found that Ancic was a crazy 16-1 to win.

Since Ancic was on the verge of winning he found it too tempting not to take advantage as his inexperience led him to believe that the bookies must have temporarily fallen asleep.

Sure enough, Ancic went on to win and my friend thought he had out smarted the bookies with a cheeky little win.

That elation was cut short when the programme cut back to the studio where he learned that the realtime Federer versus Ancic match had been suspended due to bad weather and what he had been watching was a replay from six years ago.

If bookmaking were a game it would be extremely boring because there's only ever one winner.

However, it inadvertently confirms that mis-directed beliefs play a big part in sport.

Quite often we get what we believe, but all too often find we find ourselves believing in the wrong things.
