Espanyol routed Rayo Vallecano 5-1 thanks to Kalu Uche's hat trick for its first win in six games in the Spanish league on Sunday. The Nigerian striker headed in the fourth-minute opener at Cornella-El Prat stadium. Coutinho then scored his first goals since arriving at Espanyol on loan from Inter Milan. The 19-year-old Brazilian tapped in a cross from Sergio Garcia in the 10th and slalomed through two defenders to add another in the 23rd. Uche netted with a chip shot to make it 4-0 before halftime. Former Espanyol striker Raul Tamudo pulled one back for Rayo in the 54th, but Uche capped his treble off a pass from Garcia in the 68th. Also, Atletico Madrid beat Granada 2-0. Barcelona visits Racing Santander later Sunday. (For more sports news and updates, follow Ahram Online Sports on Twitter: @AO_Sports)
