Andy is a very good indoor player but not as good as Federer because Federer has played far more than Andy and has a lot more experience. So if they both make the final here and if it rains again, then that will favour Federer again, unfortunately.
However, maybe Andy has learned from that match. He learns all the time.
Fed will always be tough to beat, as will as the two others.
We will hope. Fingers X'ed
