Today in the Telegraph there is an article about sky ITV are sets to challenge for the European football when it comes Up
Lol. I posted that link in digital spy forum to say how BT won't be losing the rights. Look at the date on the article (6th August)
Well as the article is entitled
BT and Sky get in training for their big Champions League rematch
And as as written in early August both the title of the original post and its claim to be today's news is flawed so unless an incorrect link was posted it is a surprising posting.
It is reasonable to assume that those companies that lost their previous rights would consider participating in the bidding process when those rightsnext become available.
