Barcelona were rocked by an injury blow on Tuesday night, as Jordi Alba limped out of the encounter against Borussia Dortmund.

The left-back was replaced by Sergi Roberto on the night as the two sides played out a 0-0 draw in the Champions League.

Whether Alba actually could've made a difference on the night against Dortmund, we'll never know, but many Barca fans are now hoping that Junior Firpo gets a shot at the left-back position in the Spaniard's absence.

The young defender joined the Catalan giants in the summer in a deal worth €18m (£15.9m) and this could well be his time to shine.

So far this season, the 23-year-old has made one appearance, tallying a mere nine minutes in the victory against Real Betis on matchday two.

But many of the fans believe that now is the time for him to step up and show Ernesto Valverde he is the right man for the job.

As soon as the club officially confirmed Alba's injury, many of them rushed to Twitter to voice their opinions.
