Manchester City No2 Mikel Arteta admits they had to knock Raheem Sterling's bad habits out of him when arriving from Liverpool in 2015.
He has since gone on to prove a bargain at the Etihad, but not without some considerable help from manager Pep Guardiola's backroom staff.
"He'd picked up a few bad habits along the way," explained assistant Arteta in a new book documenting the making of City's team under the current regime.
"He'd played on the inside a lot or out on the left wing. When you move to the right wing, the direction and angle of possession coming to you is very different. When the ball reached him he really had his gaze fixed on it - rather than half-touch instinctive control and the vision of what's around him."
