Juan Antonio Pizzi believes his side were beaten by Celta Vigo as they were unable to find the intensity to play three games in a week.
Dani Parejo put the visitors in front but a double from Charles ensured the points remained at Balaidos, with Pizzi pointing to the packed schedule of the last week as a reason for the defeat.
“The first half was well contested, with options for the two teams, maybe with a little more dominance from Celta, but we were fortunate enough to get the goal when they were playing better.
“From there, they pushed well up until the break. In the second half, we didn’t have the energy to counter the play of Celta, who were superior.”
Pizzi also had to contend with the loss of both central defenders during the game, as both Jeremy Mathieu and Ricardo Costa had to be replaced.
“It’s unusual to have two central defenders get injured in the same game,” Pizzi told his post-match Press conference.
“The wear of playing three games in a week is something we have to consider.
“Celta were better throughout the second-half, but we could have drawn level in the last few minutes.
“For a team that wants to take control of games we need to play to our limit, to be an uncomfortable team to defend against and be aggressive in attack.
“Intensity is a basic requirement in football.”
