City's chance to win the game is quite big but it doesn't mean if the match will be running easily for manchester city. Im sure that intermilan is also preparing everything to face city in turkey soon.
The chance is still half half for city and intermilan at this moment. City has more probability to win in the final of UCL.
I think that you can't put anyteam in the same performance. Madrid performed so badly but it doesn't mean if intermilan will be doing the same thing like marid.
you must remember it.
You don't win a match and take a title because you are a stronger team and considered to have big chance to win it. Manchester City actually are stronger and people believe if they could beat Real Madrid 4 - 0, they can easily beat Inter Milan. It is logic but football match result is not decided by logic, it decides by coaches, players and referee. 22 players and more if we count substitutions, 2 coaches and only one main referee but the referee can decide the match by his decision on field.
Inter Milan are good enough to exploit Manchester City defense and win the final by their own good effort but the referee can help them too. I don't know will the referee have the neutral performance for both teams in the match or will be skewed in either Manchester City or Inter Milan.
