Why not, they are both individuals and both great players in their own right its not as if they were joined at the hip - now thats a match I would liek to see!
I think of course they should be allowed in the final, it's not their fault that both of them, as sisters, are better individual tennis players than the rest of the competitors in female competion of wimbeldon! It just shows that the others need to try harder. If you were to stop them, do we then stop Federer and Nadal from getting into the final or competing, do we stop Lewis Hamilton getting pole position, if he gets too many in a row. Do we stop Tiger Woods from competing because he fails to lose?? I understand that it's frustrating, but if someone is genuinely excellent at something and keeps winning, it's not a trick or fraud or unfair, it just means people have to work harder, train harder and hope they do enough to get past the seemingly unbeatable!
It's not their fault that they are 2 of the best players in the women's group. They should be allowed to play each other, apart from anything else it makes good viewing!
Why not? They are both sportswoman and among the top in their field. If they didn't face each other where would that leave tennis? After all no-one said the Schumacher shouldn't race other in F1.
of course they should be allowed.If you were to stop themthen where do you draw the line.If they are better than all the rest then they deserve to be in the final - everyone else needs to pull their socks up then to be in the final. Also how can people improve if they dont play against the best. If they were not allowed to play than it would make the competition a mockery and i think a lot of the female players would become despondent - afterall what would be next - you couldnt play becuase you were fromacertain country or had won x times previouslt
