He says there's no time to dwell on the setback.
Zubizarreta said in the wake of his side's first defeat to Madrid in seven matches: "We have to recover, reorganise and have our five senses focused on Osasuna. It's time to turn the page. More than ever, it's a case of taking each game as it comes, because the league is the main competition.
"We all have to support the team through what is not an easy time. First, the league. The rest will come later," he said.
