Pellegrini was not happy with the way his side played at the Bernabue against the Primera Division newcomers.
“I am happy because we won 5-0 but leaving aside the result we did not play well,” he told Marca.
“We must keep improving. Every game is different. We had a good end to the first half but maybe we were too confident after the first goal.
“We improved in the second half and got the goals but we should have been better in possession,” Pellegrini added.
