Roger Federer will be rooting for his good mate and compatriot Stanislas Wawrinka in his semi-final against Tomas Berdych at the Australian Open tonight.
Two Swiss players are in the semis of a Grand Slam for the first time together with the possibility of an all Swiss final if Wawrinka wins and Federer topples Rafael Nadal tomorrow night.
"What I really love that another Swiss is in the semis as well. It's the first time in history for us so it's a big deal and I was very happy for Stan last night because he's put in an amazing effort in the last years."
The women's semi finals this afternoon have 19-year-old Canadian Eugenie Bouchard meeting twice former finalist Li Na, followed by fifth seed Agnieska Radwanska against Dominika Cibulkova.
