I can't see how they could throw the Saints out of the final....
If they had top secret info, it was obviously put to god use based on their performances in both games during the 1st half when the team was being ripped to pieces. Southampton's team beat theirs over the two legs, due to better fitness and performance.
I can't see how they can legally back-date a 3-0 deficit either meaning a 2-4 win on aggregate for Boro either.
Had the game finished at 90 mins last night maybe that would give a thread of creditability to this scenario, but nowhere near enough.
This doesn't detract from any offence that may or may not have been committed.... if it is proven then sufficient punishment should be handed out.
