Virgil van Dijk says he struggled to sleep after Liverpool's "total performance" against Manchester City in the Champions League.
Jurgen Klopp's men upset the Premier League leaders with a rampant 3-0 victory at Anfield in the first leg of the all-English quarter-final.
In-form forward Mohamed Salah was among the goalscorers in a complete display from Liverpool, who beat City for the second time at home this season after a previous league win.
And Van Dijk said the way Liverpool played against Pep Guardiola's side showed how dangerous they can be when they perform to the top of their game.
