Neymar added a third goal in stoppage time to seal a 3-0 win for the La Liga leaders but it was the brilliant Messi who had made the difference.

"He is just a player who is impossible to describe," Barcelona defender Javier Mascherano said. "You have to watch him."

Luis Enrique was also pleased with the way that they coped with the threat from Bayern, who apart from a glaring miss by Robert Lewandowski had few clear chances.
