LIVERPOOL — Arne Slot believes Liverpool fired a warning shot to Paris Saint-Germain of what they are capable of in a 4-0 thrashing of Galatasaray yesterday which set up a Champions League quarter-final against the holders.

PSG edged past Slot’s side on penalties on their way to winning the competition for the first time in the last 16 last season.

Liverpool were riding high at the top of the Premier League when the sides last met, but have endured a much more difficult second season under Slot.

The Reds sit fifth in the English top flight and had to come from behind against Galatasaray after losing the first leg 1-0 in Istanbul.

However, there was little doubt over the outcome once Dominik Szoboszlai levelled the tie on 25 minutes at Anfield on Wednesday.

Hugo Ekitike, Ryan Gravenberch and Mohamed Salah struck in the second half, while Salah also missed a penalty as Liverpool responded in style from being booed off after Sunday’s 1-1 draw against struggling Tottenham.

“They haven’t dropped their standards. It was hardly possible for them to improve, but they’ve been very impressive till now,” said Slot on facing the French champions.
