Jurgen Klopp believes revenge is a wasted emotion. For the Liverpool manager, Saturday's Champions League final against Real Madrid will be viewed in isolation as yet another very big game to be won.
Footballers are different, though. They are younger for a start. They are less analytical and more emotional. So things like the 2018 final defeat by Real in Kyiv linger longer in the mind. Asked about this at Liverpool's training ground on Wednesday, Mohamed Salah didn't hesitate.
'I remember when I left the field after 30 minutes of that game it was the worst moment of my career,' said Salah.
