Hi. Recently players like Goran Ivanesevic, Pat Rafter and John McEnroe said that Federer has a greater talent than Sampras. Incidentally, these are players Sampras beat on a regular basis. For instance, Sampras had a 12:4 advantage over Rafter and beat Goran regurlarly in 2 Wimbledon finals and a Wimbledon and US Open semifinal. Is it called sour grapes?
