Fair enough, although I'm talking as United fan who is fighting for 1st (which I suppose you could count as a cup) rather than an Everton fan fighting for 4th. Either way, what I'm getting at is that I'd rather we win the league by having a manager who can hold us together over a full season rather than winning the League Cup and coming 3rd.
I don't want a manager to come in because they can win us a knockout tournament, I want a manager to come in who can win us the league.
