Reina claims there is more to come from his former Liverpool team-mate as Spain prepare to face Croatia in their Group C decider tonight.
Reina said: “Fernando has never been a false number nine. He’s been showing all the time.
“Everyone has ups and downs in his career and surely he is coming up again.
“I think he was in good form, in good shape.
“He’s looking really sharp in training and that’s the Fernando I know – I’m glad for him.”
