Luis Enrique has received the backing of Andres Iniesta

Andres Iniesta and Barcelona's president have rallied behind coach Luis Enrique after fans vented their frustration at a tough week with boos during their 2-1 home win in La Liga on Sunday.

Just days after a 4-0 drubbing by Paris Saint-Germain in France in the Champions League last 16, Barcelona needed Lionel Messi to convert a 90th-minute penalty to beat struggling Leganes.

Iniesta acknowledged the defending Spanish league champions were rattled after the defeat to PSG but backed the coach and team to restore the side's winning mentality.

"We have not lost confidence in ourselves or in the manager," Iniesta told reporters after his 400th league match for the club. "I think it's a one-off situation we're going through."

Iniesta said it was understandable the team carried a Champions League hangover into the Leganes match.

"We knew it was going to be difficult after what happened in Paris," the Spain international said. "We're humans and these things affect us."

Barcelona sit second in the league table, a point behind arch rivals Real Madrid who have two games in hand. The side have also earned a place in King's Cup final in late May.

Enrique has steered Barcelona to eight trophies out of a possible 10 since taking over in 2014, but the thrashing by PSG marked the biggest humiliation of his coaching career.

Enrique's contract expires this summer, but Barcelona president Josep Maria Bartomeu said he had no intention at this stage of searching for a new coach.

"In the last few years, he has won almost all competitions," Bartomeu told reporters. "The Barca supporters are very happy with him."

"We will speak to him in April to see how he feels," Bartomeu said. "The priority is still for Luis Enrique to continue."
