In his column for The Times, Rooney said: "City play in the final third. They keep possession there. And Foden is not a dribbler but a player who plays nice little passes and moves into good positions. At City, the movement of players around him enables it.
"City will play quick five-yard passes before a little movement — not a big one — will free Foden up and he has licence to go into the spaces and play as a No 9, at times, or No 10 at others. Whereas with England he is a bit isolated out wide and when he receives the ball, the possession is slow and there is little happening around him.
"That means he then has to dribble — and if you are playing in such a way that, from your wide players, dribbling is what is required then why not play Grealish and Jadon Sancho, two of the best at doing it."
He continued: "I love Foden as a footballer but you have to realise that, for four years and more, he has been moulded into a City player.
"Pep Guardiola did not let him go on loan, or experience a different style of football — his whole adult career has been spent playing the Guardiola/City way. It is hard for him to turn up and just change how he has been playing since the age of 16"
