Barcelona sure love winning games 6-1 to complete a comeback.

Heading into Wednesday night's Copa del Rey quarter-final second leg, the Blaugrana knew they needed to produce something special having lost 2-0 last week.

And that's exactly what they did. Philippe Coutinho opened the scoring and later grabbed a second before goals from Lionel Messi, Luis Suarez, Ivan Rakitic and Sergi Roberto.

It was Coutinho's 13th-minute penalty that really got the ball rolling for Barca, though it was Messi's kind gesture that made it possible.

Messi won the penalty after being tripped in the box and, despite being Barcelona's first-choice taker, told Coutinho he could have it.

Coutinho made no mistake from the spot and after the game Messi explained his decision.

He said, per Sport: "Coutinho had scored a penalty against Levante and he wanted to take it. We talked about it, so he took it and I am happy because the comeback started there."

In his own post-match interview, Coutinho hailed Messi for allowing him to take the penalty, which inevitably did his confidence wonders.

"I tried everything and nothing was coming off," said the Brazilian, per the Mirror. "Leo encouraged me to take the penalty and that worked to help me gain confidence.

"It was not anything we had prepared, it was very kind on his part. The gesture shows how great he is as a person.

"It was a very special night for Barcelona fans everywhere; we knew that we had to come back after the bad result. We played very well and we deserved it."

Coutinho claims he was struggling to make an impact before the penalty and his highlights show how much of a difference scoring made to his confidence and performance.

For the rest of the game the 26-year-old was everywhere, receiving the ball in tight spaces, dribbling past opponents and playing incisive passes to his teammates.

Hopefully this will be a turning point for Coutinho, who has come under a lot of pressure at Barcelona recently for his inconsistent form since joining from Liverpool.

The Brazil international is a world-class talent on his day and he needs to start delivering week in week out to live up to his £142m move one year ago.
