It is the second time Messi has collected the honour and comes after he scored a remarkable 50 goals in the Primera Division - four more than Cristiano Ronaldo of Real Madrid.
"This is a group prize," Messi told Barca's official website. "I always say that when an individual wins something like this.
"That's a fact, and this one more than any. It is a prize for scoring goals, but I'd never have done it without my team-mates."
