Oh hope you have had relaxing time out at the ocean. No didn't see Tsonga match but I do think he can challenge Nole. To take three sets off Nole at a Grand Slam is a totally different matter though.
Tsonga nearly pulled it off a couple of years ago. he had nole on the ropes but let him escape.
Tsonga can do it but he will have serve very big and also be effective at the net. and of course he will have to smart on returns (return of serve) and not reckless.
he cant sit back and try to engage nole in a baseline duel.
