It might be true that Liverpool is not stronger than Machester, but I think we will see a very different game in the final compared to the Machester vs Madrid semi-finals.
Odds for winning the trophy are Liverpool 1.55 & Madrid 2.35, which is quite balanced considering earlier odds of the semi-finals when everybody thought it will be an easy task for ManCity.
Utlimatively I think Liverpool will win this game, but it won't be an easy task and might go to extra time.
Agree that Real Madrid managed to defeat City with the help of a lot of luck and the referee in extra time. Luck in sports is very important, and luck is very often on the side of the strong and persistent. But I think that Liverpool are stronger and they should win in regular time, so as not to bring the game to penalty shootouts. Why tempt fate, although in matches with Chelsea, Liverpool showed, that they can shot penalties very well.
