What a silly thread! The expectations on him are ridiculous. Calm down everybody.
It is easy for people to forget that he is still only a teenager. It is obvious that he is the most special tennis talent we have seen in quite a few decades; however, you never know what will happen with injuries in the future.
Although he has looked in fine form lately, he may not even win his first slam this year; we could be waiting until 2013—or later! The top players would have watched tonight's match ominously, and if he is seeded for the AO pencil him in for a deep run. For Wimbledon, he will obviously be one the favourites.
A safe guess would be 8-20 slams, depending on how quickly his clay game matures. Djokovic is the only current player that has proven he can match it with an in-form and serious ND.
