Mourinho coveted the United job himself.
But he says: "They have made good decisions.
"He has good experience, good work. I am more than happy, and I feel very happy for him.
"Man United will give him the time to adapt to a new dimension. He has never played a Champions League match so people can't expect him to be a fish in water in that first match.
"Give him time, stability. United is perfect for that, so that's a very good choice."
