Liverpool boss Jurgen Klopp could be heard losing his rag with his young players during their 7-2 friendly win over Blackpool.
In what was their final pre-season match before next weekend's Premier League opener against Leeds, the Reds came from 2-0 down to eventually beat their former under-23 boss Neil Critchley's side 7-2.
Joel Matip, Sadio Mane, Roberto Firmino, Harvey Elliott, Takumi Minamino, Divock Origi and Sepp van den Berg all scored for the Reds, but not before they had been given a shock by the Tangerines.
Young defender Billy Koumetio's dallying on the ball was punished by CJ Hamilton to give Blackpool the lead at the Kop end, with Jerry Yates adding a second from the penalty spot after a foul by Alisson.
With his words echoing around an empty Anfield, the Reds boss could be heard shouting "win a challenge! Start winning challenges! Be in the right place! Move!"
Eventually, Liverpool responded to his message and ran out comfortable winners.
