Andy really needs to win this, and if he doesn't he desperately needs to win at least a set otherwise his place in the competition will be relying on Tsonga winning.
I can tell you this. Even if Andy loses (God forbid), will win at least a set. Nole has more possibility to go down in straight.
I hope Andy serves very well today and starts well from the get go. First set will be the key but won't be a deciding factor.
