Liverpool midfielder Alexis Mac Allister has told his brother Kevin to prepare for a difficult night at Anfield as their clubs go head-to-head on Thursday, with the Reds taking on Belgian side Royale Union Saint-Gilloise in the UEFA Europa League.
In a heartwarming video, the siblings have reminisced about their childhood, and how Alexis had to be bribed with packets of crisps to play his first match on a full-size pitch.
But while they have a great relationship, those niceties will be put on hold for 90 minutes if they are both named in the starting line-up tomorrow.
"We're very relaxed, we've got an easy game coming up," Kevin told his brother.
Alexis replied: "Hopefully you don't enjoy it, I want you to suffer. And hopefully after the game you will not want to play against us again.
"I've been in Anfield as a Liverpool player and as an away player as well. I can tell you that as an away player you will feel the stadium and the crowd.
"After the game we can speak, but hopefully you don't enjoy it. I know you're wishing us back luck because I know how it is in Argentina. Good luck because you will need it."
Alexis's warning looks justified, given Liverpool's form this season.
The Reds had won their previous seven matches in all competitions prior to Saturday's loss to Tottenham Hotspur.
And going back even further, they have not tasted defeat at Anfield since losing 5-2 to Real Madrid in the UEFA Champions League in February.
