Up until 27th June I hadn’t heard of Marcus Willis, I’d be surprised if you had. On 29th June I, along with perhaps millions of others, watched him play Roger Federer (I’m assuming that most of you will have heard of Roger) on the centre court at Wimbledon. In a matter of a few hours Marcus Willis had become a national celebrity. I had seen a clip on the news of him walking through the grounds of Wimbledon and people were clamouring for his autograph. He seemed uncertain of what to do, as if he were a bit of an imposter but eventually he paused to sign some and those that he stopped for seemed genuinely delighted.
