I was thinking the same thing (and I still do, largely). But someone pointed out that he's only been with us for a couple of years, and he might be a long-standing Man United fan (apparently a lot of Danes are?). Lots of 'maybes' there I know, but if that scenario is true then I could see the sentimental draw of him moving to them.

It's still a really stupid decision IMO given the state of that club, but emotion isn't always rational.

Also, as for the fact that we are in need of strikers, maybe he's looked at Eddie who is about to get shipped off, and also how we've unloaded Biereth without him even breaking into the first team, and thought "yeah, I have no future here, regardless of what they say".
