Not to completely contradict my previous post, but if you're a complete degenerate gambler, you can take PSV Einhoven +800 vs Liverpool. PSV is tops of Dutch Eredivisie, and Liverpool has been playing like total crap. But cups/competitions are different from normal league play.
Taking Portland Timbers double chance only because they're my home team and have played SDFC tough the last two playoff games and this is the third winner take all to advance. They'll probably get destroyed.
