I suspect City has maybe a 75% chance of winning the league and us only about 25%... That right there is our biggest hurdle to the quad.
Maybe 55% chance of winning FA cup.
75% chance of beating Villarreal in semis and let's say 55% against City or RM in the Final.
To me that puts our odds at:
.25*.55*.75*.55
Less than 6%.
The longer City go without dropping points in the PL the lower our odds of the quad will get.
Truly can't see City dropping any points with that run-in. More likely we will. Nothing to do with jinxes, just pure, cold-hearted, dispassionate analysis, I'd be 'happy' if we pushed them all the way though. I also think if we meet City in the CL final (likely?), then they would deffo be 60% favourites. They rested key players in the FA semi-final - they won't do that in a CL final.
