Napoli coach Carlo Ancelotti has named David Ospina in his squad for tonight's Serie A opener against Lazio.
Ospina joined Napoli on-loan from Arsenal on Friday.
The Colombia goalkeeper signed his contract in the final hour of the transfer window on Friday.
He had travelled with his new teammates to Rome for the game, but was not officially in the squad.
Now that he has been formally registered with the Lega Serie A and given international clearance by Arsenal, Ospina is added to the list of players available for selection.
