The Italian talked up the Reds' attacking prowess and isn't sure any side can match the firepower of Mohamed Salah, Sadio Mane and Roberto Firmino.
He told the Mirror's David Maddock:
"Liverpool have a very strong team—but I do especially look at their front players.
"With Salah, Mane, and Firmino they have so much pace, so much creativity, and of course they are all big goal threats.
"Throughout my career I have always wanted to test myself against the best—and at the moment you really can't think of any teams in Europe who have a better front three than Liverpool."
The trio haven't quite produced the same blistering form they enjoyed last season, but they have contributed a combined 21 goals and eight assists in this campaign.
Salah scored his ninth of the season last Saturday as the Reds beat Watford 3-0 in the Premier League, earning praise from football writer Joel Rabinowitz:
Sports journalist Jack Sear was also impressed with Firmino and Mane:
Firmino got on the scoresheet to end a six-game goalless drought while Mane grabbed an assist, so all three are coming into Wednesday's clash with PSG on the back of a good performance.
Buffon has perhaps neglected his own front three, however, as PSG trio Kylian Mbappe, Neymar and Edinson Cavani would dispute his comments.
They've been in electric form all season—Mbappe and Neymar in particular—producing 36 goals and 17 assists between them in all competitions.
Their performances have played a large part in the Parisians winning all 14 of their matches in Ligue 1.
However, in a difficult Champions League group that also contains Napoli and Red Star Belgrade, PSG haven't been the same force on the European stage, having collected just five points from four matches.
Though they'll back themselves at home, they're right to fear the damage Liverpool's attacking stars can do.
Salah, Firmino and Mane will be crucial to the Reds' chances of coming away with a positive result, but the performance of PSG's front men will also have a significant impact on the outcome.
