Jurgen Klopp slammed for selling the 27-year-old powerhouse

Liverpool let their ‘best defender’ go when Mamadou Sakho was permitted to join Crystal Palace in the summer, as suggested by Phil Thompson.

France international Sakho moved to the Reds in 2013 from Paris Saint-Germain, however, fell out of favour with Jurgen Klopp the last term.

The 27-year-old was sent out on loan to Palace for the second-half of the last campaign and impressed as the Eagles bypassed relegation, eventually ending 14th.

However Sakho failed to win over Klopp, and the defender was sold to Palace on last day for a fee understood to be worth around £30million.

“Our best defender at the start of this season has been allowed to leave, Mamadou Sakho was our best defender. He was a warrior, a fighter, a battler – all those things and you saw it at Crystal Palace last season.

“He was like that at Liverpool. I know there are fallouts in football all the time, but somewhere along the line, you can’t cut off your nose to spite your face.

“He should have made up with the boy, ban him for three or four months and then bring him back in.

“And now you lose out to Van Dijk for whatever reason that happened so surely you would be keeping Sakho.” – Thompson, who played 400 games for Liverpool, told Sky Sports.
