These two guys have always entertaining matches, they both are offensive players. Previously Federer has been the better claycourter, and he beat Tsonga in straight sets in their only encounter on clay in Rome 2011. But Roger hasn't been too impressive recently and Jo has improved his clay game, I'd say Jo has been the better player at RG this year so far. But Roger only needs to bring his best game from last years, and he can win this. But I still believe in Jo winning. Clayga 2.0 CONM to win in four sets.
