Speaking after the draw at San Mames, in which the reigning champions failed to find a breakthrough to open the scoring, he defended his team-mates.
"It's taking advantage a bit, when the results aren't coming, to say that the squad is weaker," he said.
"Our squad is just as competitive as last year, and we haven't had all of the squad available yet because of injuries and that's important."
That's not to say that the squad are perfect though. The former Malaga man recognised that a lack of goals are costing his side.
"Today is a clear example that we are lacking goals," he continued.
"Maybe that's what is costing us."
