Liverpool boss Jurgen Klopp made a request of Mohamed Salah that he has never made of any other player during a match on Thursday.
The Egypt international scored in the 6-1 Europa League demolition of Sparta Prague to bring up his 20th goal of the season, becoming the first player in the club's history to reach that mark in seven successive campaigns.
He completed his first 90 minutes in two months but Klopp admitted that he wanted to take him off earlier and asked him to do something unique.
