Call me crazy, but I honestly think that we (Atletico) would have fared pretty well against Liverpool in a CL final. Granted, they would probably hammer us severely at their own stadium, but in a neutral venue- I think we would have the upper hand...
Real Madrid, despite having a much worse and less organized defense than us, were able to effectively neutralize them in the final last season. I think we would have been able to snatch a tight 1-0 victory over them, although then again, it's a CL final- virtually anything can happen...
If you do a side-by-side comparison of each player in their respective position, there really isn't a massive gap in quality:
Defense (back 4):
Godin<Van Dijk (though I personally think Godin in his prime was a superior CB)
Gimenez>Matip (not even up for debate- even Hernandez, a natural full back, would make a better CB than Matip)
Lucas Hernandez=Robertson (okay, I have to admit I'm being a little biased here, but hear me out, both full back's are a lot closer in terms of quality than you think- Robertson may offer more in terms of offence, but I personally think Lucas is more reliable when it comes to defending).
F. Luis<Trent Alex Arnold (Luis in his prime was without dispute far better)
Midfield:
Saul>Wijnaldum (can honestly see Saul becoming a genuine candidate for the best DM in a few seasons from now)
Koke>Milner (pretty close contest here, but have to give it to good old Koke for his superior passing abilities)
Partey=Henderson (just about even- Partey has speed and agility on his side, though Henderson arguably fares better in terms of tackling)
Forward:
Antoine>Firmino (not much debate here really)
Lemar<Salah (same as above)
Correa<Mane (kind of unfair to Correa, as he tends to operate most effectively as a dual striker)
Swap Lemar with an excellent winger on pare with theirs (Neymar, Hazard, Dembele, Zaha, Richarlison) and I think we would be genuine favorites...
Had to delete my previous comment- wouldn't post for some odd reason...
