He signed for the Blaugrana on a free transfer earlier this week. He'll play at Camp Nou for two seasons with the option for one more year with a buyout clause of $438 million attached. 

Is Gündogan set to inherit Busquets' Number 5 shirt?

While Gündogan's preferred jersey numbers, 8 and 21, are already in Pedri and 's hands, are circulating about what would be the perfect fit for him. 

Kit numbers are scarce in Hernandez's squad, with eight numbers up for contention. Yet, Gündogan does have some hope in acquiring the iconic number 5 shirt from Sergio Busquets. 

The Spaniard emerged as the second ex-Blaugrana luminary to join the ranks of MLS side Inter Miami. Busquets opted against renewing his contract at Camp Nou, thus departing as a free agent following a legendary 15-year stint at the club.

The number 5 suits Gündogan. The elastic midfielder is in the leadership mold of Busquets, both acting as a coach on the field as former captains of their clubs.   

The number 18 is also an option, as Jordi Alba could be on his way to Inter Miami.
