Noni Madueke has been warned to maintain the standards and 'behaviour' he is showing now to continue to thrive at Chelsea.
Manager Mauricio Pochettino took a subtle shot at the attacker when he said it took him 'six months' to figure out what is required.
Madueke arrived to great expectation from PSV Eindhoven a year ago, joining in a £28.5m deal, but it has taken time for him to crack the first team.
The 21-year-old has had a peripheral role to this point as he adapted to Pochettino's demands - but things now look to have clicked.
