Maxi/Downing is a really frustrating conundrum to have, in my opinion.
On the one hand, Downing is a much better footballer. More pace, better crosser, and with the ball at their feet they're about the same. And yet Downing would never have scored the goals Maxi scored last night, especially the first one, because he's never in that position. It's not that he doesn't get there consistently, it's that he never, ever makes that run. I'm not sure why he's allergic to getting into the box, but he is, and I think at this point we have to realise he's not going to get it with further coaching or more encouragement. It's simply not part of his game.
So, though Downing is a better "player," in the sense that we're talking simply about what he does with the ball, he shouldn't get in the team ahead of Maxi, because Maxi scores goals. And goals are what we as a side are crying out for.
