Madrid-Sana
Barcelona have announced the return of Lionel Messi to play after recovering from a calf injury.
"Messi is back and that means only one thing, beware, world," the official Barcelona website said after the match against Dortmund.
On Tuesday, Messi made a partial comeback in the second half of Barcelona's 0-0 draw at Borussia Dortmund at the start of his Champions League campaign after being sidelined for 115 days.
The Argentine, who has been the top scorer in the Primera Liga for six seasons, begins his career at La Liga this season, five goals behind Villarreal striker Gerard Moreno, who is the top scorer in four stages.
