Many people already expect Manchester City will win from the first leg, just take a look at the odds. On the first leg, Manchester City was slight favorite team and the second leg, Manchester City was heavy favorite team. Real Madrid wasn't playing very good in the first leg which is Real Madrid's home, so it's not really surprised why Real Madrid can play so poorly on the second leg.
In the first leg Real Madrid performance was not convincing to defeat Manchester City, I was not too expecting much from Real Madrid in the second leg. And it was too obvious in the second leg to see Real Madrid not having good strength to challenge Manchester City. Manchester city were able to score without any resist from Real Madrid.
This will be interesting how Inter will prove to everyone if they able to beat Manchester City.
I don't think Inter will be difficult for Manchester City, Manchester City already have the Champions league by succeeding defeating Real Madrid.
