The deciding round was an anagram round of 5 male tennis champions.The first couple went for Rafa Nadal and the second couple for Bjorn Borg.Despite the anagram showing Rafael Nadal they let them have it saying it was difficult to pronounce his name.So is an anagram an anagram or isn’t it.
They've disallowed many answers in the past for wrong pronunciation, i have thought at the time that it seemed to be a bit harsh as they knew the answer.
