Video: Top eight men's players talk about fears, kisses and actors

Sky Sports caught up with the eight competitors at the ATP World Tour Finals and asked some in-depth, probing questions about fears, future casting decisions and first kisses. Each of the eight players quickly shows their true personalities (which isn't necessarily a good thing, BERDYCH) so it's a fun way to spend a few minutes:

Observations:

• "Really? OK, spiders."

• Federer definitely remembers the name of the first girl he kissed. He either doesn't want Mirka to know or it's Mirka and he doesn't want us to know.

• Also, it's no surprise that David Ferrer remembers so quickly.

• "Toothbrush." /falls asleep

• Good to see they wedged in a clip of Tomas Berdych. Just imagine how boring his other answers were.

• "John."
