Thomas Tuchel has had a good start to the season in his first few games in charge of Paris Saint-Germain, winning five league matches out of a possible five, as well as beating Monaco in the Trophée des Champions.
However, none of those games have been particularly challenging for the Ligue 1 champions, but Tuesday evening could be very different.
The German manager will have to find a way to best Jürgen Klopp and his Liverpool side, who have also started the season in great form, equalling Paris Saint-Germain’s record, but in the Premier League.
One of his major worries will be how to keep Mohamed Salah in check, as many would say the Egyptian poses a greater threat than Sadio Mané or Roberto Firmino, at least individually.
The 19-year-old has already featured in four games this season, and he picked up two assists against Monaco in his side’s 4-0 win.
As challenges go, this will most likely be his biggest one to date, and it will be interesting, if he does indeed start, to see how he fares against such an illustrious opponent.
