Sorry Andy, but beating this guy will be a stretch

Federer keeps his emotions in check – most of the time.

Murray, 22, is still on the young side. He expresses raw emotion on the court – he demonstrates a self-talk, pump-up style that burns up too much energy.

Fed will use his grand slam experience to his advantage. He will out-manoeuvre Murray in a clinical and calculated way.

Federer won’t have too much trouble in his semi-final clash against Frenchman Jo-Wilfried Tsonga.

Tsonga has fought out some tough matches this tournament and he will front up tired for his semi-final clash.

Fed is just so calm and controlled. His calmness saves him plenty of energy. He draws strength from his seemingly relaxed demeanour.

However, under that calm exterior, Federer’s mind is constantly ticking – mostly about strategy and how to outwit his opponent.

It takes a lot of maturity to play with controlled emotion. It takes a lot of practice too.

Federer’s supreme mental toughness is the underlying current of his success - his consistent performances in grand slam finals.

For years, Andy Murray has worked liked crazy to win a grand slam.

And the way Murray played against Rafael Nadal on Tuesday night (before Rafa pulled out injured), there were signs that the Brit (Scot) is close to winning the big one.

Murray will learn from this grand slam final – how to save his energy on the big points, and how not to let the adrenaline zap him during major finals.

Good luck to Murray. Good luck to Federer. But the simple fact is ... Murray is not ready to take the crown away from Fed.
