Jose Mourinho is confident Chelsea can come back against Paris Saint-Germain in their Champions League quarter-final second leg at Stamford Bridge tonight.
The Portuguese insisted his players have enough quality to overcome the two-goal disadvantage against the French champions, and promises the game will have goals in it.
"I think we are going to win, really. In the end of the two legs, I think we are going to score more goals than them," Mourinho said.
"I believe, the players believe, the reasons are not the most important thing. We need to win. The players have to show their quality, confidence and ambition. All the qualities you need to play at the top level.
"In this moment it's 3-1, I think in the end it can be 4-3 or 5-4. The only thing I know is that if we don't score a minimum of two goals we have no chance.
“If they score one, we have to score three, at least. If they score two, we have to score five. This is the only thing I know. The basic thing of the numbers, the basic mathematics."
Mourinho was adamant that PSG remain the favourites for the tie and insisted an exit of the French ‘multi-million’ pound club would be an upset.
The Portuguese also highlighted that PSG has enough quality in their squad to cope well without their injured superstar, Zlatan Ibrahimovic.
"How the game is going to be, I don't know really," Mourinho added.
"They can say they come to attack and maybe they don't cross the midfield line. Maybe they say they come to defend and they find spaces and score goals. We don't know.
"I think if Paris (Saint-Germain) is knocked out, it will be a big disappointment for them. If tomorrow we are knocked out it's something, in this moment, that lots of people are expecting.
“The fact that a multi-million pound club that buys players and players does not have important player like Ibrahimovic, I don't think it's a problem."
