Man City has more league titles in the last 13 years (8) than any NFL team has Super Bowls in its entire existence (6).
Bayern Munich won 11 consecutive titles, a run that ended last year. No team in American sports can match that to my knowledge, not even the Celtics of the 60s.
Real Madrid has won more CL titles in the last 10 years (6) than the number of World Series the Yankees have won in the last 40 years (5)
PSG has 10 titles in the last 12 years. Only 3 NHL teams have that many Stanley Cups over their entire existence, and 2 of those teams are based in Canada.
