With the eyes of a nation on him, Andy Murray plays in the Wimbledon semi final tomorrow. Commentators say he looks more comfortable then ever. Will this be the year he maintains his confidence and focus to finally make the final?

Andy Murray is a modern day warrior and he can win this easily. All he needs to do is follow the philosophy of the greatest warriors in history; the Samurai. They followed the rules of Bushido and incorporated Zen meditation into their beliefs in order to calm the mind. They also valued honour above all else.

Murray is already far along this path and I like to think it is thanks to my art teaching.

Andy Murray's Wimbledon chances

I constructed this Samurai costume and for the last two years I have attended all his most important matches to send him an important message through art metaphor. I wear the outfit and sit silently in the crowd, just in the corner of his eye, as an ever present reminder of the calm and focus he should be aiming for.

During his quarter final match to Nadal two years ago, when I sensed him flailing during the match, I stood up suddenly and violently to show Murray he was not alone. Sadly, he faltered soon after. He must not have seen me.

Last year, as he battled Andy Roddick, I stood in his line of sight and performed several manoeuvres from ‘the way of the sword’, inspiring him to draw on their ancient strength. Disappointingly something seemed to distract him in the crowd and he was defeated soon after.

This year I have decided to prepare for longer and more subliminially, appearing and then disappearing suddenly at Murray’s training sessions, restaurants, bathroom window etc, in the hope that he will be in a constant state of alertness and this will have him prepared and calm come match day.

We can only wait to see if he is as composed as my art should have inspired him to be. Oh and also, during the match, I think I might perform fake Hara-kiri, the Samurai practice of ritual suicide, if he is looking too unfocussed and to also serve as a nice reminder that death is preferable to a dishonourable defeat.

GO MURRAY!!
