You're actually incorrect. You can both have a good run in a cup and perform well in the league. That's actually the most common scenario.Simply reflecting on your posts .
I know you’re disappointed with our League form ; but any 8-year old understands that there are both swings and roundabouts; eventually as you grow older you’ll realise you can’t ride both at the same time .
Have fun on one or the other if you can’t do both ; you actually may enjoy life more that way .
We could've won that cup with any manager. That both Man U and Spurs reached the final despite their terrible form should be enough to understand that the competition isn't exactly top notch.
For some reason you seem to think it's childish to call things for what they are. Can't please everyone I suppose.
