Roger Federer believes Rafael Nadal is still the favourite for the French Open despite the Spaniard's recent struggles. Nadal suffered his earliest exit in 12 years at the Barcelona Open last week with a third-round defeat by world No 29 Fabio Fognini and has admitted his confidence is lacking. World No 1 Novak Djokovic is 30-2 so far this season and became the first man to win the first three Masters titles of the year after his triumph in Monte Carlo.

Federer said: 'At the French Open, Rafa for me is still the favourite alongside Djokovic who has been playing so well. 'Even though his (Nadal's) form is not as good as in previous years, I still believe when the French Open rolls around he is going to be very difficult to beat.'
