Hello,
a question to the native English speakers around...
In French, when a player lost many time against another player around his rank, we say it's his black beast.
Example :
- Gaudio was the black beast of Ferrero till Ferrero beat him in Monte Carlo before to win Roland Garros
- Nalbandian was the black beast of Federer in 2003 (he very likely made him miss the year end 1st rank place, by beating him 4 times this year, including the US Open & Melbourne)
So my question is :
What is the good way to say "black beast" in English ?
