Outgoing Barcelona boss, Luis Enrique claims his side have the firepower to stick 6 goals past Paris Saint-Germain as they attempt to make Champions League history by overturning a 4-0 first leg deficit on Wednesday.

"If they can score four goals against us, we can score six," said Enrique on Tuesday.

"We have nothing to lose and a lot to win."

The fierce criticism that came Enrique's way after their humiliation in Paris 3 weeks ago has eased after he announced last week that he will step down after 3 seasons.

Rather than show any ill-effects from Enrique's decision, optimism in the Catalan capital of a stunning fightback has soared after thrashing Sporting Gijon and Celta Vigo 6-1 and 5-0 respectively in their last two outings.

"Despite the fact that the result from the first leg is very one-sided, we are only halfway through the tie," added an uncharacteristically buoyant Enrique.

"In 95 minutes, an infinite amount of things can happen.

"I am convinced that at some point we will be close to qualifying.

"That isn't to say we will do it, but that we will be close. And, when you are close, our confidence will soar and theirs could start to diminish."

No team in the history of the Champions League has ever turned around a four-goal deficit.

An away goal for PSG would mean Barca would have to score at least six to have any chance of reaching the quarter-finals for a 10th straight season.

Barca are at full-strength with captain Andres Iniesta replacing Rafinha or Ivan Rakitic likely to be the Enrique's only change from the side that thrashed Celta at the weekend.
