Lucas Alcaraz lambasted his Granada side for a nightmare five minutes as they lost 3-0 to Rayo Vallecano.
Goals from Saul Niguez and Joaquin Larrivey in the 54th and 59th minute gave the Madrid-based team the lead, before Seba Fernandez completed the win in the final moments.
“In five minutes it went away from us completely,” he told a Press conference.
“We were unfortunate, but we shouldn’t have let it happen like that.
“I am convinced that this team will succeed though. We’re good enough to stay up.”
