Here’s a doozy of a dilemma for you. When the world’s top 8 men’s tennis players are walking towards you on a chilly London night on the Greenwich peninsula, dressed to the nines, heading to the O2 pier and a ferry to take them to the opening gala for the year ending ATP World Tour Finals, who do you get? Signature wise, I mean.

I had sketched them all and some of their high profile coaches – Boris Becker, Michael Chang, Amelie Mauresmo…

Security warned the small group of us waiting that they were late and in a hurry. Nothing new there. I calculated that I only had a few minutes. There was one other ‘grapher in the group, the rest were after selfies – that could slow them down a fraction…

Because Andy Murray wasn’t at last year’s event, he was my top priority. In fact, I actually had two sketches of him, but he has a quick siggy and is always obliging. Mission accomplished and both signed – one even dedicated. This is the other one.

For the record, on that cold November evening I managed to get Roger Federer, Stan Wawrinka, Kei Nishikori, Boris Becker and Andy of course. Not a bad harvest in two minutes!
