Raheem Sterling needs to raise his game even further to match the best players in the world and must train even harder to do so, says Gary Neville.
The England international forward has been integral in Manchester City's title-winning campaign, contributing 17 goals and 12 assists as Pep Guardiola's side secured the Premier League with five games to spare.
However Sterling has been accused of being wasteful on occasion, such as in the 3-2 defeat at home by Manchester United, where he missed several chances to win City the game – and the championship.
