Roma performed brilliantly throughout the final match between Sevilla vs Roma. But their misfortune is a suicide goal. Had it not been for the own goal in that match, Roma would have won the UEFA Europa League title. Roma equalize with Sevilla through own goal. And in the end Roma were badly beaten on penalties.
I mean anything can happen in the final match.
At top level, difference is very small and winner, loser can be decided by only one moment. Roma did bad penalties and deserved to lose on that spot but within 120 minutes, they actually deserve to win than Sevilla. Before that final, Roma were considered as weaker than Sevilla but in that final, they played better than Sevilla. What they lacked is luckiness and support from referee like Sevilla.
That is, even if Manchester City is ahead throughout the entire game, if such an unexpected event happens at the last minute, then there is a possibility that we will lose the bet, so I am reluctant to bet win or lose because of this fear.
Inter Milan actually are very good with Catenaccio and counter attacking. If Manchester City fell to attacking too much but failed to create advantage, they will open some space for Inter Milan when they are chasing for goals. Inter Milan have many players who can create good exploitation against Manchester City within 90 minutes or 120 minutes. I agree with you that Manchester City must have goals as domination in an entire final match will not make them as a winner.
