Levante goalkeeper Oier Olazabal has warned Kepa Arrizabalaga over his imminent move to Real Madrid.

The Athletic Bilbao keeper is set to join Real next month.

However Oier, who is a former Barcelona keeper, says Kepa must be wary of the ruthlessness at Real.

He declared: "I think he'll adapt, but at Real they do not forgive.

"Keylor Navas had an amazing year, but last season we started to say he was not good. Sometimes when you are good, you are told the opposite and you start to hesitate.

"In Madrid, a mistake in the Champions League or in another important match, and they give up on you."
