Yes, agree also. Fed showed that he can beat Rafa on clay, which he did in the first 7 games, and in the third set. Take the ball on the rise, take chances, rush the net, serve and volley, etc.
Then Fed falls back to his old habits, first allowing the ball to rise too high on his backhand, then after a while his forehand goes spraying balls too.
The tennis.com analysts said it simply: Nadal's topspin forehand to Federer's one-handed backhand is a battle that Federer cannot win. Therefore Roger has to change his game plan.
