My roommate is a big Man-U fan and we have football going in the background most of every day. I don't have any real favorite team (though I do support the Portland Timbers and the US National teams), but I think Man-U definitely improved itself by getting rid of Fail-Cow and adding Schweinsteiger. Now the only question is whether de Gea will stay with the team or not - the weirdness at the end of the season seems to indicate not, but who knows?
On an individual basis, I'm definitely a fan of Harry Kane. What setups and finishes! Seems like he's always in the right place, plays for his childhood favorite team and doesn't seem to have the pompous attitude that so many of the best have.
