Valencia's trip to Mallorca should also be interesting, though I'm predicting a home win, and things to get worse before they get better for Koeman.
In other notable games, Barça should have an easy home win against a terrible Betis side, and Levante probably face a last chance to save their season as they host fellow potential relegation battlers Almeria.
