Gavin Mairs in the Telegraph says Stade Vélodrome in Marseille is the front runner for 2020 with competition from the new White Hart Lane in London. Amsterdam are bidding the the hosting rights in 2021. Can't complain. Turn the final into an event and have major cities bidding for it rather than simply rotating it around the home stadia of the old 5 Nations. It's probably for the best limiting capacity of stadia in emerging markets to 60000 to avoid the spectre of a half full stadium.
