Thomas Tuchel has received harsh criticism from former PSG manager Luis Fernández, who claimed the German coach is "way off" the level of Europe's best trainers and has offered little in Paris.
QSI, headed up by chairman Nasser Al-Khelaifi, has overseen a dramatic overhaul at the French club, revolutionising the facilities and bringing in big names such as Zlatan Ibrahimovic and Neymar in a bid to secure Ligue 1 dominance and win the Champions League. Elimination by Manchester United left a scar a year ago.
PSG's mercurial Brazilian star Neymar has angered club bosses after preparing for his side's UEFA Champions League clash with Borussia Dortmund by jetting to Dusseldorf in Germany for a red carpet fashion event.
The most damning of failings for Fernandez, nonetheless, was the way in which his old club were unloaded out of the Champions League by Manchester United, with a dual from Romelu Lukaku as well as an additional late fine, racked up by Marcus Rashford, reversing PSG's first-leg triumph.
"We won't take any risks, obviously, but at the same time we'll put out a strong team", Tuchel had said at his pre-match press conference on Friday, prior to naming his squad. Failure to reach the quarter finals this time around would likely spell the end of his time in Paris. "The owners expect to get to the final".
