Wilson Palacios isn't signing with the Union and he could possibly be a decent pickup. I don't know anything about him at all except he played for Stoke.
He was solid on Spurs a few years back. Strong, can rip a long range shot in every once in a while, but prone to a lot of stupid fouls, takes a lot of dives and I'm sure by now is probably not as fast as he used to be. Definitely could enforce in the midfield though.
