I don't really watch tennis (or much of any sport bar my own), but I'm pretty much in awe of top level tennis players. The level of mental strength and concentration required to play at the top level must be amazing. To keep the concentration up after you lose a point you should have won, to not let it turn into a route when the other player has the upper hand for a bit. I've seen so many sports people just going "lol, i quit now*" when things aren't going my way that Murray impressing me a lot by fighting till the very end and literally refusing to give up, ever.
* not literally quitting but quitting as in "I won't try anymore"
