Liverpool defender Mamadou Sakho has “let himself and his club down badly” with his failed drugs test, according to former Reds centre-back Jamie Carragher.
UEFA is currently investigating a possible anti-doping violation by Sakho, who failed a drugs test after Liverpool’s Europa League second-leg tie at Manchester United last month.
It is understood the failed test is associated with a fat-burning supplement and Sakho, who was pulled out of Saturday’s game against Newcastle but has not been suspended either by Liverpool or UEFA, now faces an anxious wait to see whether he will receive a playing ban.
The France international is likely to ask for his B sample to be tested, with the deadline for that request set for Tuesday.
Carragher, whose one-club playing career came to an end with his retirement in 2013, told Sky Sports on Monday: “It’s a nightmare for the player.
“I think he’s let himself and his club down badly, because he was becoming a really important player for Liverpool.
“There are serious questions to be asked of him.
“He’s had a great campaign. He’s one of the leaders of the team now. You think of the Borussia Dortmund game, the Manchester United games especially, how well he played in those. It’s now how Liverpool fill that void.
“But for a professional footballer – or any sportsman, really – it’s not acceptable.”
