He's a great captain and one freak occurrence, that is over magnified because of the context and because it's Utd, doesn't change that. If you don't feel he'd fit in tactically in your team that's fine (though I'm pretty certain any top manager would take him and make it work, as they do with any top player), but this is somewhat ridiculous - he's much more of a leader than most of your players.
It's also hilarious that you would highlight his moaning when your team is full of moaners, Odegaard being at the top of that list. And I'm sure you consider him to be a great captain.
They were poor in the knock-out games and were ok in the groups - they also lost to Lens and drew to PSV. Overall their European season was underwhelming, which is not great when you're calling yourself "one of the top teams in Europe" as most of their fans do. This, coupled with the early exits in domestic cups, also gives a bit more context to their season last year.
I believe they'll be better in Europe this year though.
