After being drawn in a group alongside Napoli and PSG, it is not a surprise that Klopp's team have still not guaranteed a place in the next round.
Precisely, their European future will be defined against those two strong squads, even though the defeat against Red Star might be eventually decisive. Today, they visit Paris knowing that a draw would be a good result considering that on the last day Napoli will visit Anfield Road.
There, Liverpool have won their last four European matches, always scoring a minimum of three goals.
In fact, the Reds played at home their best football of the season, when they won against PSG in a thrilling match which was decided on a late Firmino's goal.
PSG and the years of misery
Since Nasser Al-Khelaïfi became the chairman of the French team in 2011, they have been winning many titles in the country. And yet, after so much money spent, they have not even reached a Champions League semifinals.
Despite having Neymar, Mbappe and Cavani, perhaps the most talented trio of attacking players in the world, they have been eliminated in two consecutive seasons in the second round of the competition.
Especially painful was their defeat against Barcelona, when they lost the draw in spite of winning the first-leg by an astonishing 4-0.
And just one year later, they were thrashed by Real Madrid in Paris, in spite of that the French were leading on the Bernabeu, and for most of the time, controlling the match. But this season might be the definitive failure if they get out in the first round.
The final at Wembley
In another decisive match for an English squad, Tottenham Hotspur must win against Inter Milan if they want to have a chance to progress. Certainly, the late come-back suffered as visitors in Italy are proving to be, as it was predicted, a burden hard to overcome.
Even though the Londoners won tonight, probably they would have to beat Barcelona at the Camp Nou.
To do this they must show more quality and effectiveness. Currently, just the two goals of Kane in the last match have given some hope for Pochettino's team.
Indeed, the prospect to fall into the Europa League is as certain as it is daunting. Nevertheless, this competition might serve as a redemption for Arsenal and Chelsea, which are clearly improving during the season and yet, knowing that a place in the top four of the Premier League could be eventually out of reach, they surely will need to prioritise in order to achieve their aim.
