Jurgen Klopp has warned Liverpool to be braced for a Manchester City 'thunderstorm' in Tuesday's showdown for a place in the Champions League semi-finals.
Liverpool's hopes of protecting the 3-0 advantage they gained at Anfield have been boosted by Mohamed Salah's recovery from a groin injury picked up in the first leg.
But Klopp is wary of City starting the match as ferociously as they did the Manchester derby, when they led 2-0 inside half an hour.
'It was one of the best first halves I ever saw,' said Klopp.
