As previously quoted, BT can blow Sky out of the water financially and Sky know it!
They have a war chest set aside to buy as many sporting events as possible, if you need further proof , look at the figure they paid for exclusive CL rights.
Next up is the EPL rights , and make no mistake, BT will massively outbid Sky and win 75% of the coverage including Super Sunday.
I have dealt with BT Sports Commercial Director and this comes straight from the horses mouth.
