When I watch those old matches as today between Borg and Gerulaitis I laugh. This is old, very slow tennis ( it is why it is full of great points). I don't want to say those players are not great, no. But those old champions can teach Federer nothing including Roche. In order to win FO he must hire somebody from fresh list ( who reached the final at FO or won it). Imagine, even Kafelnikov - recent FO champion ( recent means of last 10 years) told there is nothing he can advise to Federer, only be patient, because atacking tennis doesn't win on clay ( Sampras, Becker, McEnroe and etc...). Who are possible contenders ? I seriosly think about: Kuerten, Lendl, Wilander.
