What should happen to Manchester City?

My opinion is a simple one. For sure they (Man City) should be deducted enough points to relegate them, plus a transfer embargo. A huge fine, and force the current owners out of English football. That's what I think the Premier League should do. I would love for Man City to be pushed as far down as non league football but that can't happen because the EPL only run the Premier League. It's nothing personal against Manchester City, but this has affected the outcome of leagues, and a lot of football clubs who have been in the Premier League and participated in Cup matches home and abroad. Not to mention the unfair advantage Man City have had over all the teams they have played over the season's in question. On top of that it's had a knock-on effect regarding the transfer of players. One thing is for sure it's going to be interesting to see what happens in this case.
