Lets not fool ourselves, the United Treble was a major achievement, they competed in 3 competitions, and whatever you think both the European Super Cup, and this world club cup are just 3 games max. What would be incredible is to win all the domestic stuff like City did last season, and also to win the CL. My biggest fear is that City were very close to doing that last season, and until it becomes obvious that they cannot win the title, it is still a possibility this season that they could achieve this.
But City's achievement last season was incredible and is still better than what we have achieved, mainly because of the number of games they have had to play to win those competitions. Our showing in the domestic cups has been pathetic for the last 3 seasons, and by opting out of those games, has given us an advantage to further our progress in the league, and CL.
