"We deserved something more than a defeat," Lopetegui said.
"We had a good first half, we scored a legal goal, I'm sure not sure why they ruled it out, I'm not seeing it.
"We didn't start the second half well with the ball. Then we took risks, we scored and they went back in front soon after,
"We took risks and we had Jesus [Navas]'s pass in behind and the shot from [Youssef] En-Nesyri.
"I really don't understand, unless someone can help me understand, why the goal was ruled out.
"I think it's a massive error."
