They won their first Ligue 1 title this century in 2012-13. Having won every league title since then except 2016-17 and 2020-21, there is no doubt about their dominance in France.The same cannot be said about their results in the UEFA Champions League, though.

However, they will have their task cut out against the 13-time winnersOn that note, here's a look at five PSG players who could be key against Real Madrid tonight:#5 Achraf HakimiManchester City vs Paris Saint-Germain: Group A - UEFA Champions LeaguePSG's lack of world-class full-backs has haunted them in the past. The Mauricio Pochettino-coached side had no answer to Bayern Munich's Joshua Kimmich and Alphonso Davies in the 2020 final. With attacking full-backs being the norm across Europe, PSG bought Achraf Hakimi for €66.5 million last summer.Hakimi started his Ligue 1 career with a bang. He accumulated three goals and two assists in the first two months of the campaign. The Moroccan has been an ever-present for the French side in the Champions League as well, having playing all 540 minutes so far.GOAL@goalAchraf Hakimi doesn't mind that Real Madrid let him go 🤷‍♂️5:33 AM · Feb 14, 2022260031171Achraf Hakimi doesn't mind that Real Madrid let him go 🤷‍♂️ https://t.co/TSUHMVUOmNThe 23-year-old could be key against his former club on the defensive side of things. Vinicius Junior has been on fire this campaign. However, Hakimi is one of the few right-backs in the world who can match the Brazilian's pace. The tussle between the two youngsters could go a long way in determining the game's outcome.#4 Gianluigi DonnarummaParis Saint-Germain vs Manchester City: Group A - UEFA Champions LeagueGianluigi Donnarumma has been in a rotation with former Real Madrid goalkeeper Keylor Navas. Although both of them have played three games each in the Champions League this season, the Italian is expected to feature against Los Blancos tonight.Donnarumma has done reasonably well in his maiden Champions League campaign. Not only has he made more saves than Navas, but he has also conceded fewer goals and saved a penalty too. The former Milan star will hope to keep a clean sheet at the Parc des Princes tonight if he starts.GOAL@goalThe world’s best goalkeeper in 2021 Gianluigi Donnarumma wins the Yashin Trophy 2:01 AM · Nov 30, 20218878717The world’s best goalkeeper in 2021 👑Gianluigi Donnarumma wins the Yashin Trophy 🏆 https://t.co/Oq9BCUJq2NReal Madrid have been indifferent in front of goal recently, scoring just once in their last three outings across competitions. Considering the same, the PSG shot-stopper will fancy his chances of replicating his shutout against Manchester City in the group stage earlier this season.
