It was briefly mentioned on the build up to one of England's matches in the tournament
Sterling was getting criticism from the media about his performances and especially the number of times he was losing the ball whilst trying to take a man on
The commentator (or expert who sits with the commentator) said that "the England coaching staff were surprised by the criticism of Sterling as he was doing what they asked, be aggressive with the ball and take a man on, and they also believed he was one of England's better performers"
But I don't ever recall Hodgson telling the press this in one of his tournament interviews
