Lionel Messi believes Barcelona must avoid Real Madrid’s mistake of being arrogant and keep their feet firmly on the ground.

Messi was speaking at a benefit for Unicef, and took time to respond to Real Madrid's disappointing exit from the Champions League.

"We have come here to speak about Unicef, but I will respond to your question," said Messi. "We have a match against Stuttgart in which nothing is definite and we need to take what happened at the Bernabeu as a warning.

"We have to have our feet on the ground and think of ourselves.

"We always try to approach each match with humility. Last year we had the fortune of winning everything, but this year we start at nothing and we have to work hard to win things".

Asked if he was needed to carry La Blaugrana during matches, Messi humbly denied these opinions.

"I do not go out with the team on my back and I didn't do it last year. It is very difficult for one player to win titles alone."

"We are playing well, but are not achieving results."
