On paper and the way the teams played their last few games and overall the entire season, I also think that Inter has no chance here and Guardiola will finally lead the Citizens to win the UCL... still, in football we never know and over the years we've seen bigger and bigger upsets in all competitions and especially those European competitions were really 'unpredictable' lately(not only UCL, Europa League and Conference League had their share of 'surprises' too), so honestly if Inter wins the trophy in the end IMO it won't be the most unpredictable outcome...
