Ferran Torres described his Paris Saint-Germain debut as "special" as his second-half brace helped Luis Enrique's side come from two goals down to draw 2-2 with Rennes.

The defending Ligue 1 champions were staring at a shock opening-day defeat when a Sebastian Szymanski stunner and Esteban Lepaul's finish put Rennes in control. 

But after Khvicha Kvaratskhelia and Ousmane Dembele were replaced at the break, with Ferran and Mika Godts introduced into the action, PSG improved significantly.

Ferran pulled one back in the 71st minute when he finished past Brice Samba at his near post before the World Cup winner sealed a share of the spoils eight minutes from time with an inch-perfect header from Fabian Ruiz's cross. 

And with his inspired display, Ferran became only the third player in PSG's history to net a brace on his debut, after Zlatan Ibrahimovic in 2012 (versus Lorient) and Patrick Mboma in 1994 (against Vac FC in Champions League qualifiers).

The result saw PSG start a Ligue 1 season without a win for the first time since Luis Enrique's very first game in charge, though, and Ferran acknowledged improvements were needed. 

"The match was difficult. It was complicated, we're not happy because we wanted to win, but it's important to leave with a draw," Ferran said. 

"It was special to play my first match in front of the Parisian fans, and it will be even stronger at the Parc des Princes.

"My relationship with Fabian Ruiz? With his quality, we just have to run and put the ball in the back of the net.

"It's a great group, I knew it was before I arrived, there are only good people, great players on a daily basis, who have helped me feel good here."

Ferran's impressive display even drew praise from Rennes goalkeeper Brice Samba, who conceded his team let a golden opportunity for a win over the champions slip away. 

"All credit to Ferran Torres, a new world champion in our league," Samba said. "We saw all his quality, even if I think his two goals are largely avoidable with a little more concentration and a little more freshness.

"Overall, it was a good performance against the two-time European champions. We took a point and we'll move forward.

"We wanted to win, especially with the scenario of the match when you are winning 2-0, but we're not going to be picky, it's a point and we're moving forward."

But it was not all smooth sailing for PSG. They struggled in the first half, generating an expected goals (xG) total of 0.59 from their 10 shots, with Luis Enrique making the decision to withdraw to big hitters Kvaratskhelia and Dembele. 

That decision proved to be merited, given PSG have now scored 31 goals via substitutes in all competitions since the start of last season, at least six more than any other side.

And when asked for the reasoning behind his decision to replace Kvaratskhelia and Dembele, Luis Enrique said: "That's football. That's how football is. PSG didn't win anything.

"If you think about what you've won, you're not going to win anything. For me, the most important thing is that there is no credit.

"You have to show every day, every practice, every game, that you're ready, otherwise it's easy to rest. No.

"We're looking to win all the time and to win all the time, you have to get out of your comfort zone, that's clear."
