According to uk.sports.yahoo.com, the Argentina worldwide set up Luis Suarez for an equaliser after Girona had taken a third-minute lead, and netted twice himself, the second an inventive free-kick steered under the opposition's defensive wall at Camp Nou.
Here's Messi's goal late in the first half to make it 3-1.
He added another goal six minutes later with a superbly struck free kick that he sent low under the players in the defensive barrier when they jumped, anticipating he would try to shoot over them.
One man who was desperate to see the Brazilian swap Liverpool for Barcelona was Luis Suarez, who explained recently how much he's seen Coutinho change over the years. Coutinho finally got on the scoresheet with a lovely curling shot that went in off the right post.

Messi got onto the scoresheet on the half-hour mark in typical Messi fashion as he squared Bounou up with a few touches before slotting an effort past the goalkeeper's outstretched hands into the corner from 12 yards out. "Just when you think you've seen everything from Messi, he surprises you, like his free kick, which looked easy but was very hard to execute", Valverde told Movistar Partidazo.
"They are players who have to help us and who are already doing it, each with their own characteristics".
"Dembele offers more width, he's a winger and he's still very young". He's had problems with injuries, meaning his period of adaptation was skipped.
It was Barca's 32nd league game unbeaten, a club record surpassing the one set by Guardiola's side in 2011.
