do you realise that in the first ten years of the premier league united were more dominant than city are now? (city have won 5 in ten years, united won 7 in ten years)
did that kill the premier league as a spectacle?
equally the winning margins united had were on average bigger than citys winning margins
united 18, 11, 10, 10, 8, 7, 4 (average 9.7)
city 19, 12, 2, 1, 0 (average 6.8)
also add in 5 different champions in the last 10 years as opposed to 3 different champions in the first 10 years when united won 7.
where there has been a change is the number of teams in the top 4.
7 different teams in the decade city have been dominant
10 in the first decade of the premier league
however that change happened before city owners arrived, the ten years before they arrived there were 7 different teams
