Well they also made it to a CL final
There was A LOT of luck involved there.
With them getting away with a clear handball vs Barca in the group stage, which played a massive part in them making the knockout stage.... and then getting an incredibly easy draw in the KO stage.
Bayern emasculated them in the group stage and got rewarded with PSG & Man City (and Real Madrid if they wouldve beaten City) in the KO stage. Inter got Porto, Benfica, and AC Milan. Credit to them for beating those teams, but they've been far from impressive and havent beaten anyone that would impress you.
They're in better shape right now than Juve, sure. But Juve are a lot closer to Inter than Inter are to the elites of Europe. I fully expect City to dominate Inter and make a mockery of the final.
