Zubimendi left Real Sociedad for Arsenal this past summer.
"He’s a great player,’ Rodri said ahead of Spain's World Cup qualifying win against Turkey. "He has the discipline and mentality that can lead him to become one of the best, if he isn’t already.
"I spoke to him the other day and told him it was his time, that I was leaving him the keys to the team."
Rodri also reflected on winning the Ballon d'Or last year. The midfielder was recognised just months after suffering an ACL injury.
"The injury is much more significant than the Ballon d’Or," he added. "It was a breath of fresh air at a time when I was having a really hard time. I’m happy for the recognition."
