Maybe, but City winning the league puts them so much closer to the quadruple. City's squad depth is better than any of the other teams left in the CL and they're clearly decent in one-off games and knockout competitions. In all honesty, they're the last team I'd want to play in the final. United fans should be careful what they wish for.
their record in CL knockout ties
2014 - Barcelona (L)
2015 - Barcelona (L)
2016 - Dynamo Kiev (W), PSG (W), Real Madrid (L)
2017 - Monaco (L)
2018 - Basel (W), Liverpool (L)
2019 - Schalke (W), Spurs (?)
When it comes to teams they actually beaten in a single leg, Dynamo Kiev, PSG, Monaco, Basel, Schalke and lost games to Barcelona, Real Madrid, Monaco, Basel and Liverpool - so going off their recent past they’d probably beat spurs and lose to Juve after that
