Mohamed Salah's Champions League final motivation was summed up is a six-word tweet posted moments after Real Madrid completed a dramatic resurrection against Manchester City to set up a meeting in Paris.
"We have a score to settle," announced Salah, a superstar of few words but barely able to conceal the hint of menace in his message to the team responsible for the worst night of his Liverpool career.
When Liverpool meet Real Madrid in the Stade de France on Saturday, memories of a balmy May evening in Kyiv four years ago - when Jurgen Klopp's side were beaten 3-1 - will be painfully revived for Salah.
