Don't really agree. I'd take gradual progress in the PL over PL standstill and a couple of FA cups any day.
Trophies matter, but so does context. The thing that matters is: Are we genuine contenders for the PL title?
If the answer is yes, Cups and european trophies matter. If you're a genuine contender for the PL title, then you are in a position to win, and that should extend to cups.
If the answer is "no", then let's face it - a cup or a Europa League is really just a consolation prize. They make no fundamental difference. Maybe they're important as stepping stones, learning experiences - but that's about it. To me, how we do in the FA Cup or Europa League this season doesn't matter much to how I judge this season, one way or another. And I don't buy into the "this is United, there's got to be trophies" thing. If we're not challenging for the league title, what the feck does it matter whether we win the League cup or not?
