The Liverpool defender was on form against Borussia Dortmund on Thursday night.
The Reds netted a priceless away goal in Germany and Sakho was vital as Liverpool battled against a number of potent Dortmund attacks.
At one point, the centre-back made a sensational block in the first half - and Lineker responded shortly afterwards, praising his defensive skills in the face of an 'awkward' playing style.
Sakho may look awkward and always on the brink of stumbling over the ball, but he's an exceptional defender. #DorLiv— Gary Lineker (@GaryLineker) April 7, 2016
They reacted on Twitter to Sakho's block itself, although Dejan Lovren made a similar one minutes later.
My god ! What a block Sakho— Ian Wright (@IanWright0) April 7, 2016
Klopp has transformed the Reds' defence within months in a manner Brendan Rodgers couldn't do in years.
The decision to play the hard-working Divock Origi up front was also testament to Klopp's tactical thinking on Thursday. He offered far more than Daniel Sturridge could've off the ball, as good a finisher as Sturridge is.
