The key matchup here is Elche's defense, which has given up 42 goals this season, trying to contain Valencia's attack, even if it's been inconsistent.
Valencia, sitting 10th in La Liga, hasn't exactly been lighting it up, but they're coming off a solid 2-0 win over Osasuna. Elche, meanwhile, has been battling, but their last three games include a 3-0 loss to Real Betis and a narrow 2-1 defeat to Mallorca. They've only managed two wins on the road all season.
Valencia gets this done at home. Prediction: Valencia 2, Elche 0.
