The key matchup to watch here is how Mallorca's robust defense handles Rayo's attacking fullbacks, particularly Isi Palazón on the right. Mallorca's recent form has been patchy; they just snapped a four-game winless streak by beating Granada 1-0, but before that, they'd conceded five goals in two matches against Barcelona and Real Madrid. Rayo, on the other hand, has drawn four of their last five, including a gritty 0-0 at Getafe last weekend. This feels like a cagey affair. I'm taking Rayo Vallecano to edge out a 1-0 victory.
