It doesn't happen often that Nadal is an underdog against anyone. But I was expecting that especially after last round clashes. Nadal is week, him, Fedex, Delpo they are all flat, tired, and I'm really worried about level of this year London finals. I think Nadal is suffering the most, he is not the same player, Nadal without his fighting and pushing abilities is very, very unconvincing. In my opinion this match will be much similar to final against Davydenko. Tsonga is a kind of Davydenko from Shanghai here, if his wrist will be alright I think French man have big chances to steal London spot once again, he feels so free on Paris courts and he is a wonder kid who can produce incredible tennis, out of nowhere, without any previous destroyer form flashes. In my opinion only Djokovic and Cilic are able to threat him here. Nadal was struggling against even Robredo, a baseliner, who Nadal used to eat alive in good days. Tsonga would have to lower up his level a lot to let Nadal win this game in state he is right now. And besides Tsonga is kind of train in tours, further he goes better he plays.
