Messi fires Barcelona progress 6-1on AGG.

Title favorites Barcelona travelled to Shakhtar Donetsk

Shakhtar enjoyed some decent early pressure and goalkeeper Victor Valdes was forced into saves from Douglas Costa and Jadson.

World Player of the Year Lionel Messi hammered the ball into Donetsk's keeper momentarily.

Just before halftime, Fullback Daniel Alves picked out the Argentine striker and he held off three defenders before slotting low past Andriy Pyatov. It was his ninth Champions League goal of the campaign, putting him top of the scoring chart, and a club record 48th of the season in all competitions beating retired Brazil forward Ronaldo's mark.
