The off-the-field behaviour of Liverpool winger Raheem Sterling has become a "distraction", according to former defender Jamie Carragher.
Sterling, 20, has held talks with Reds manager Brendan Rodgers after being photographed using a shisha pipe and appearing to inhale nitrous oxide.
"Even if you don't talk about it, it is in the background," said Carragher, 37.
"Rodgers is asked the day before a game, when he should be talking football he's thinking about Sterling."
Carragher, who made 737 appearances for Liverpool - below only Ian Callaghan in the club's record-appearance list - also believes Sterling's interview with BBC Sport - unsanctioned by the club - was an issue.
Sterling explained he had turned down a new contract offer worth £100,000-a-week but said he is "not about the money".
"As young players, and I have been guilty myself, we have made mistakes but hopefully this will be a maturing point for him," Carragher added.
Asked if players would intervene in this situation, Carragher, who was speaking at the Telford Tigers' end of season awards, added: "If it continually happens you know you've got a problem and you may need to pull someone and have a word with them."
