Portugal coach Carlos Queiroz believes Cristiano Ronaldo will only get better as a Real Madrid player.
The former Manchester United assistant manager told the Daily Mail: "Playing for Real Madrid was his dream and this will make him stable. He will improve as a player, too, because he will have to think more.
"Most teams in England have the same tactical approach, 4-4-2. In Spain it could be anything from week to week, so you have to consider the game in a more tactical way. And, also, he is more mature - that is the main point.
"You cannot compare a 24-year-old with a teenager arriving for his first season in England. He is not a kid coming in at 7.30am anymore, listening to the adults talk while he eats his breakfast."
