IMO, it makes United's summer that much more interesting. They're on a pretty great run right now, including convincing wins against their two biggest rivals. Should the plan be to stick with this kind of lineup and tactics, maybe buying a few upgrades (a better winger to replace Young, an elite CB) but basically staying with the same plan, including Fellaini/Rooney in the 9/10 roles? Or do they change things up significantly? Its kind of a puzzle because Fellaini has been such a critical player for them and one wonders whether they could play the same way without him. And, of course, there is the question of where (if anywhere) Di Maria fits into the equation.
