Well, you eliminated the financial benefits of getting rid of rooney from consideration by dismissing it as something that fans shouldn't care about as its something for accountants. I just highlighted how ridiculous that claim is. Anyway, your point doesn't make sense, wanting rooney gone now and being a United supporter are not mutually exclusive, regardless if he can be replaced now or not.
As previously said, the minutes wasted on him could/would go to better players.
Rooney is reportedly on £250k+ a week, that's hardly "a drop in the ocean" and could go a ways at setting up early summer deals to strengthen the team.
"Experience" is one of the most overrated intangibles ever. Rooney's footballing ability and physical prowess have abandoned him to the point he can't translate supposed "experience" into something substantial. If anything, more often than not, he's detrimental to our play.
Yeah, he's our captain, in title mostly these days, he's a squad player that's hardly on the pitch not to mention armband was handed to him by a different manager.
