Can't understand people saying the titles shouldn't be awarded to the team who placed second in each respective season. In athletics, dope disqualified athletes are stripped retrospectively and their medals handed down to the next on the roster; in football, Juventus' titles went to whoever was not involved in the scandal who was the next closest to them; Lance Armstrong's titles would've been passed on if the whole sport wasn't bent. I don't know if there are examples for other team sports, but handing titles to the would-be legitimate holders is hardly unprecedented and nor should it be.
As for the relegation aspect and all the fallout with regard to what happens to all the other clubs impacted, it should be a mess that is sorted out, not swept under the rug - and I'd be amazed if each club who were majorly compromised don't have their lawyers pawing other the minutiae of this case
This is unprecedented cheating, which should come with unprecedented review and overhaul with no stones left unturned or brushed over for the sake of convenience. This isn't about United or whoever being awarded tainted titles, it's about the next in line being the rightful owners of those titles with their efforts not simply swept under the rug - whoever entered a campaign above board and competing fairly for the trophies at stake has every right to claim them over any club(s) that didn't.
This isn't the 80's or even the 90's where the proceeds of profitable offences were kept in lieu of time served for the crime in question, nope, now you serve time and you're stripped of all the proceeds of said crimes. Absolutely no ill-gotten trophies should remain, and nobody but the offender should be punished for their cheating, which is essentially what's on the table by not awarding the rightful parties what is fairly theirs.
