Just personally I'd rather see Andy play Rafa on grass or hard, but the draw is what it is. Andy can't turn round and pick who he plays or tell the organisers that he doesn't fancy playing Rafa on clay (might be fun if he could, on both counts lol), he has to get on with it, so we should as well.
Rafa hasn't played the new, confident Andy Murray. Rafa hasn't played Olympic Gold medalist and US Open Champion Andy Murray. I know they were on different surfaces, but still. Confidence goes a long way in tennis.
If they both get that far (nothing certain about either of them yet, a ball is yet to be struck) it will be interesting to see how Andy does against Rafa now. A win would be fabulous. I think it would do such a lot for Andy's confidence, and it would give Nadal something to ponder over. I'll think about any other outcome when/if it happens. Until then it's one match at a time. I bet Haase can't wait to play Andy again
