Lionel Messi warned his Barcelona teammates not to repeat their Champions League collapse to Roma at half-time in his side's ill-fated semi-final second leg against Liverpool last season.
Going into the Anfield match, Barça were 3-0 up in the tie but after the first 45 minutes the Reds had pegged them back with a goal from Divock Origi.
The comeback threatened to be reminiscent of Ernesto Valverde's side's 2018 quarter-final capitulation, when Roma managed to overcome a first leg deficit of three to knock Barcelona out.
Because of this, Messi gave a rousing half time speech ahead of the closing act of the Liverpool tie earlier this year.
In footage that originally appeared on the club's 'Matchday' documentary on Rakuten TV (via Marca), it has been revealed exactly what Messi said to his teammates.
"Come on, guys, let's take a step forward. We can't pass up this opportunity," Messi began.
"Give it your all, we're there. We're going to start [the second half] strong. Remember, what happened at Roma was our fault, no one else's. Don't let the same thing happen again. It was our fault and nothing more."
The speech would prove largely ineffectual, with a brace from Georginio Wijnaldum and a clever corner routine involving Origi and Trent Alexander-Arnold ensuring that Liverpool overturned the visitor's three goal advantage and progressed to the final.
The Reds would go on to lift the Champions League trophy, defeating Mauricio Pochettino's Tottenham 2-0 in Madrid.
Barcelona have not won the Champions League since 2015 but have made a solid start to their campaign this season, with a 3-1 win over Borussia Dortmund last Wednesday ensuring top spot in Group F with a game to spare.
Valverde's side also sit atop of the La Liga table despite having already lost three games this season.
