Berlin, April 18 : Ronald Koeman has revelled in his first title as Barcelona head coach but has set his sights on clinching the La Liga crown. Barcelona lifted the Copa del Rey with a 4-0 win over Athletic Bilbao in Saturday's final, marking the Dutchman's first title since taking over at Camp Nou in August, DPA reported. The Catalans lost the Supercopa final to Bilbao in January and exited the Champions League in the last-16 to Paris Saint-Germain. Barca are firmly in contention in the league, sitting third, two points behind leaders Atletico Madrid in a three-horse race with Real Madrid too. "To win a title is important for me," Koeman said. "Despite the changes at the club and the young players, at Barca you have to always fight for trophies." "We have the first one and now we are going to fight to the last game in La Liga." Saturday's victory was earned with four second-half goals, with Antoine Grizemann breaking the deadlock on the hour mark. Frenkie de Jong doubled their advantage on 63 minutes, before a Lionel Messi brace rounded out an emphatic win which Koeman said they deserved. "A result like this is not normal, but we deserved the cup," Koeman said. "It took us a bit to score, but we had chances. Our possession has been good and after 1-0 we have dominated the game with great football in every way. "We have been at an extraordinary level. We deserve this cup." /IANS
