Mamadou Sakho could miss the start of the Premier League season after suffering a new setback in his attempt to re-start his Liverpool career.

The 26-year-old has picked up an Achilles injury that could rule the central defender out of his side’s key Premier League clash against Arsenal on 14 August.

The news will frustrate manager Jurgen Klopp who has has seen his defensive options depleted after releasing Kolo Toure and Martin Skrtel’s impending £5.5million move to Fenerbahce.

The France international missed out on this summer’s European Championships after being suspended from football following a drug-related charge that has since been dropped.

“Mama had a little issue with his Achilles when he was playing, one day on, one off, this kind of thing,” Klopp told the Liverpool Echo.

“When he had his little ‘break’ he used the time to have a little bit of treatment and that now means another three or four weeks before he can train again.

“There was no surgery, he is just not about to train at the moment. He has got some rehab of course and it’s not too good a situation for him, for us, for everybody.”

The Reds ace is currently exploring the possibility of legal action against UEFA after being cleared of violating drug laws.

In other Liverpool news, Reds boss Jurgen Klopp has told Mario Balotelli that he must leave Anfield this summer.
