For the world number 772 to be playing Roger Federer, arguably the best male player ever, on Centre Court at Wimbledon is amazing.
It's just a great story that's happened to a really good fun guy, and it's nice that the public seem to have taken to him. If he was an absolute prat I'm sure some people would just think, 'He's an idiot, I'm not interested', but he's definitely the kind of person who deserves this moment.
I haven't seen Marcus Willis much over the last four or five years but whenever I've spent any time with him, he just makes you smile and laugh.
