I think his aim is to Consume Nanjirou's tennis. If I'm right then what he really wants is to play against someone that has the Radiance of the Strong Heart, that doesn't exist in Europe and is only seen in the heart of a samurai or something like that. This way Ryoga would be in the finals with Consume AND Q.P.'s God Aura.
Meanwhile Ryoma would probably need to acquire something new as a counter, perhaps an Aura that is only unlocked by someone that has the three Radiances themselves.
Against Consume, if Muga isn't instantly consumed itself, copying techniques might get him a good amount of points.
