Barcelona coach Josep Guardiola still has concerns about his team, despite another thumping 6-0 victory over Valladolid in the Primera Liga. Samuel Eto'o hit four first half goals at Nou Camp to help Barca cement their position on top of the table. However, Guardiola believes the scoreline did not reflect the genuine image of the game. "The score is a little unreal and deceitful," the Barca boss said after Saturday's game. "In the first-half they had as many counter-attacks as we did but they have not finished and we on the other hand have been clever because we have decisive players. "It is not normal to score six goals in a match and I believe there are things we can improve on. "For example the start of the second-half was not so good. There are always things to work on for we are not yet a perfect team. We have not won any titles yet." Guardiola hailed goal hero Eto'o, who put his name on top of the scoring charts with 13 goals, but conceded that the Cameroonian cannot perform alone. "Eto'o has had a fantastic season. Against Malaga he did not score but he helped us massively. He is in great form and I am convinced that alone he would do nothing and he needs his team-mates," he added. Barca maintain an outstanding goalscoring record in the league under Guardiola, who led the team to scoring 34 goals in 10 games.
