They are not thinking of the present, since the present shows Tsonga as the world no.5 and Ferrer about to lose no.6 to Berdych.
They are just not thinking at all. Or maybe they thought the question was "Who is better at winning Mickey Mouse clay tournaments?"
Yes, but Tsonga is playing awful tennis at the moment while Ferrer is sort of doing a bit better right now. Tsonga's ranked higher now because he's made up ground at the start of the year after the start of last years crap results. And that helps because since he's ranked high, no matter how shit your playing, you can get past low-ranked opponents in the opening few rounds. Ferrer shows he's been consistent comparing from last year around this time. But he's in no way better than Tsonga overall. But I will say that at this current moment, based on form, Ferrer is the better player right now.
The real question is for the posters, "Will they stop being delusional?"
