Inside the Stamford Bridge tunnel there is a carpet displaying a motif - the Road to Lisbon - the city that will host the 2014 Champions League final.
For Chelsea, if the Blues are to reach the tournament's climax, that road will be a rocky one as there is a pothole right in front of them - a PSG shaped one - as the Ligue 1 team will look to protect a healthy 3-1 advantage built up from the first leg last week at the Parc des Princes.
Much has been made over the absence of talismanic striker Zlatan Ibrahimovic, yet manager Jose Mourinho doubts PSG will be impacted too much as they are blessed with a talent-rich squad thanks to considerable investment in the past seasons.
He even compared the Zlatan loss to Chelsea not being able to field Mohamad Salah, who is cup-tied due to his earlier participation in the competition with previous club FC Basel.
"The fact a rich club, who buys lots of players, doesn't play one important player like Ibrahimovic, I don't think is a problem," Jose is quoted to have said by Sky Sports.
"Samuel Eto'o didn't play for us in the first game. I am not sure he will play the second game. Ramires is suspended. Nemanja Matic and Mohamed Salah cannot play for us in the Champions League - and we are not crying."
Chelsea recently beat Stoke City 3-0 and Mourinho is confident the club can register a similar result later this evening.
"I think we are going to win - really. I think at the end of two legs, we will score more goals than them. It is currently 3-1, and I think it can be 4-3 or 5-4."
Considering the domestic form of table topping Liverpool and the two games in hand that Manchester City still have to compete, Chelsea could fall behind in the race for the Premier League crown, leaving them desiring further progression in Europe to keep their season alive.
Even Frank Lampard cited this match against PSG as their most important of the season so far: "It certainly is our biggest game of the season," he told Evening Standard. "We want to go through, we want to win the Champions League as everyone else does.
"A fast start is very important. It’s not about getting carried away but we need to show that urgency and attack in a fast way. Closing them down fast, moving the ball fast, if we can do that and play to our game, we can give ourselves a chance."
