I hear ya general masterclass.
when considering what nole is up against, he has done quite well. he has had to deal with Federer, rafa, and andy murray.
that is big time competition.
as for RG, I don't think it will happen this time for nole. rafa will use those 4 losses in a row to be properly motivated and properly focused to deal with nole at RG.
also this is the last card rafa has left to play: he loses the king of clay title to as well as his #1 rank both at the same time if he allows nole to win in paris.
finally betting against rafa at a RG final is just a bad bet. rafa has to try to hold on to his conquered territory and I believe he will. it is his last stronghold.
he will not allow the final to go beyond 4 sets if he faces nole in the final. that is how I am seeing it.
