Jurgen Klopp has warned Liverpool will need to up their game when they tackle the 'King of Cups' after sealing their place in the Champions League semi-finals.
Liverpool reached the last four of this competition for the third time in five years after drawing 3-3 at Anfield with Benfica; a 3-1 win in Lisbon last week had given Klopp's side a significant buffer and they led by the same score here at one stage.
But once they had gone 3-1 up, thanks to a double from Roberto Firmino and Ibrahima Konate's header, Liverpool lost concentration and allowed Benfica to restore parity.
