Luis Enrique believes Barcelona can feel confident of beating Paris Saint-Germain and topping UEFA Champions League Group F.

Barca heads into Wednesday's group stage finale at Camp Nou knowing only a victory will do if it wishes to leapfrog French champion PSG for the top spot.

Both teams have already qualified comfortably for the knockout stage, but PSG sits a point clear of Barca at the summit with just one game remaining — thanks in no small part to its thrilling 3-2 win over Lionel Messi and Co. in Paris in September.

But with the likes of Bayern Munich and Chelsea having already secured first place in their respective groups, Barca and PSG know how important winning the group could prove ahead of Monday's last-16 draw in Nyon.

And Barca coach Luis Enrique is confident that his in-form side — which has won its last seven matches in all competitions — can claim the three points it requires from what promises to be a tense evening in Catalonia.

"I don't know if it is the best moment to play PSG, but it is certainly a good one," said the 44-year-old, who will be without suspended fullback Dani Alves. "We are playing a rival which has made things difficult for us with their quality, so the clash with PSG is a wonderful, perfect match.

"We know that any winning result works for us, and we are going to fight the same way that we have since the beginning of the season."

In order to win Group F, however, Barca needs to do something no other team has managed this season. Following its 2-1 win over Nantes on Saturday, PSG now stands as the only team in any of Europe's top five leagues not to have lost a game in any competition this season.

Laurent Blanc's side has won 15 and drawn eight of its 23 matches thus far in 2014-15, with last weekend's victory against Nantes coming courtesy of a brace from former Barca striker Zlatan Ibrahimovic.

Blanc is well aware that PSG is set for its sternest test yet, and has called on his players to up their game ahead of their crucial trip to Spain.

"We're happy to have won [against Nantes], but we will need to improve to get a win against Barcelona," said the Frenchman, who played for Barca for one season in the 1990s.

As is the case for any team visiting Camp Nou, keeping Messi quiet will be key if PSG is to escape with a result. That will be easier said than done, though, as the Barca talisman heads into the game in scintillating form — even by his own exalted standards.

Messi netted a third hat trick in his last four appearances in Barca's 5-1 rout of neighbor Espanyol on Sunday, and was also on target in the defeat at Parc des Princes earlier this season.

Winner takes the top spot. I don't care who wins, just want to see Zlatan and Suarez score shikena

Barca wins + both teams to score. That is 1+
