Croatia needs a win to advance to the quarterfinal round. Lithuania has clinched, but has equally as much to play for as a loss would leave them playing the US in the opening round. That is essentially a death sentence, so they aren't likely to take this game off.
Croatia has some elite scorers, but looked awful in their shocking loss to Nigeria two days ago.
Lithuania is the better team, and I think they pull it out tonight in the final game of group play.
