Liverpool boss Jurgen Klopp has words with Mamadou Sakho

Sakho has not played for the Reds' first team since April, when he was suspended following a positive doping test.

The case was ultimately dismissed by UEFA but Sakho was then sent home by Klopp from the team's pre-season tour to the US for breaches of discipline.

An Achilles injury meant the 26-year-old was not available for the start of the season but he further inflamed things with Klopp by taking to Snapchat last weekend to claim the club were not telling the truth and that he was fit.

However, he returned to action for Liverpool in an under-23 game against Wolfsburg on Wednesday night, playing the full 90 minutes.

He is well down the pecking order in terms of the first team but has been given at least a glimmer of light.

And Klopp was keen to stress his other players must also tow the line having called the squad together for a meeting.

Asked if Sakho should work hard and keep quiet to try to earn his place back, Klopp said: "Those two things are not a rule for Mamadou Sakho, it's a rule for every player - work hard and give your best.

"I spoke to the team and I spoke to Mama and we spoke together and that's it. From my side everything is done and now we can carry on."

Sakho's comments came in the early hours of last Saturday before Liverpool thrashed Hull 5-1 to continue their hugely encouraging start to the Premier League season.

It was the Reds' fourth win from six matches this season, during which they have scored 16 goals, and their third in a row.

They sit in fourth place in the table ahead of Saturday's trip to Swansea, five points adrift of leaders Manchester City.
