Newcastle boss explains Rozehnal axing
"He's a terrific lad, who's done even better than I had expected already by playing a number of Premier League games one after the other."
And now Big Sam feels Rozehnal - who will take on Germany with the Czechs on October 17 - will be better for his experience.
He added: "My job is to allow some time to sit down, reflect and learn.
"A little bit of a rest is sometimes the best thing to do.
"And I felt that was the right thing to do based on our performance at Manchester City."
