Philippe Coutinho warned by Gerard Pique of the way he treats Barcelona fans

Gérard Pique warned Philippe Coutinho to respect Barcelona fans.

The former Liverpool playmaker was whistled by supporters for his performance during Barcelona's 3-1 win over Rayo Vallecano at Camp Nou on Saturday, which ended with a 10-minute replacement the end.

Coutinho has scored eight goals for the Catalans this season, but only three since October and looks short of confidence.

Football mirror revealed that the Brazilian had made an appeal to Manchester United.

And Spades, who scored Barca's first goal, estimates that Coutinho's charges before the 100 million pounds mean he's judged harder.

He said: "Philippe is having a good season.

"Obviously, its cost was very high, which means that the expected level of performance is higher, that's what it is.

"We have to accept the reaction of the fans because they are our followers, but from the inside we have to give him our support – we need him at best for the end of the season and I am sure that it will be. "

The goal of Pique canceled the opening of the match by Raul de Tomas, player on loan from Real Madrid. A penalty from Lionel Messi at the start of the second half gave Barca the advantage. Luis Suarez maintained the points.

The win allowed Barca to restore his seven-point lead over Atletico Madrid, himself eight seconds behind Real, but Pique has not yet eliminated his big rivals despite the crisis that ravaged the Bernabeu.

"We can not reject anyone until it is mathematically about it," he said. "The other teams can hurt you, it's nice that we have a gap with Atletico."

Rayo remains in trouble after a sixth consecutive loss, but his manager, Michel, was satisfied with the qualities demonstrated by his team.

On rayovallecano.es, he said: "We have worked very well as a team, very close to each other, much better than the previous days, and thanks to this way of working, we will be able to come out from below.

"I always have confidence in my team, nothing can make us give up, we are in a complicated situation but we have to fight for salvation."
