Adam Johnson may still be revelling in the praise he has received from scoring Sunderland's winner against Newcastle United yesterday, but Craig Bellamy doesn't feel he should rest of his laurels.
Bellamy, who teamed up with Johnson in his playing days at Manchester City, feels that he has not reached his full potential.
The 27-year-old has shown his ability in fleeting patches throughout his career, but Bellamy feels that he must become more consistent if he is to ever become the player he threatened to be as a youngster.
"Ability-wise, he was exceptional when he first came to Man City, when I was there," the Sky Sports pundit said. "He's a really likeable kid, a great personality."
"He's a player I always track and I'd love him to do well in his career. But, with the ability he has, he hasn't kicked on nowhere near to the ability he really has."
"If he could play Newcastle every week, he'd be playing for England all the time! But he's quick, he can go both ways, he's got a great shot on him and he's an intelligent kid. I'd like to see him do well."
Johnson should be full of confidence to kick on after his winning goal, too. He showed great composure in the last minutes to score the solitary goal of the match with a well struck shot.
It was a huge moment for his side, as not only did it give them a record breaking fourth consecutive win over their rivals, but it also propelled them up the table.
Sunderland are now in 14th spot in the Premier League table and only four points behind Newcastle, who they will be looking to catch over the Christmas period.
