Different mental approaches of the top pros
One way of dealing with the mental pressure of a tennis match is to work yourself up into a frenzy of utter hatred of opponent. Whether you lose a point or win a point, whether you're losing the match, even, or way ahead, you visualize pummelling your opponent to the floor, kicking his head until his neck snaps, using a hammer to smash his eye sockets until his brain is mush...etc... This is a great way of remaining mentally tough and I think it is the approach that Nadal uses. I personally use this approach, not only in tennis, but in my career and all walks of life as well.
Federer uses the 'I'm better than you' arrogant mental approach, yet it breaks down against Nadal.
If you use the former mental approach, I believe you will have no trouble remaining mentally tough against any player, whereas if you go in with Federer's more arrogant attitude, if a player has beaten you in the past, doubts will creep in.
