Barcelona have registered Robert Lewandowski, Franck Kessie, Raphinha and Andreas Christensen ahead of this weekend’s league fixture against Rayo Vallecano.
The LaLiga clash will be played on Saturday from 8pm.
Jules Kounde has, however, not been registered by the Catalans.
Barca were able to register the new signings after raising £85million from selling 24.5% of Barca Studios to Orpheus Media.
Ousmane Dembele and Sergi Roberto have also been registered after agreeing new contracts.
Barcelona are yet to complete the transfer of Marcos Alonso from Chelsea and Manchester City’s Bernardo Silva remains a top target
