The reason people single Rooney out is, aside from multiple england managers(probably at the urging of the FA for monetary/sponsorship reasons) keep playing Rooney which keeps hurting the team.
When we play him as a lone striker, he drops deep, wants to be the main man on the ball all the time and is cack. When we tried him as a number 10 starting him deep so he could get on the ball and do what he wanted, he was cack. When we played him wide left, he drifted into the middle, tried to get on the ball and be the main man, and was cack. Rooney basically once in the whole game looked like a left winger and...... created a goal. he won't stick to a position and hurts the team, and that is his fault. Him consistently being picked when he hasn't done anything to deserve it isn't his fault. But he could and should still have done better and played the role he was given better than he did.
Rooney dropped, with Sterling wide and Barkley/Lallana central. Maybe drop Welbeck as well, all the closing down is useless when the final ball is crap, and he didn't close down when it really mattered at that corner. Actual quality in the final third means more goals scored.
