The Colombia international is on-loan at Napoli to the end of the season.
Hernan Ospina told Radio Crc: "David is doing well and has recovered after an immediate bad blow.
"We are waiting for a dream to come true because the number 25 game will unlock the right of transfer on the part of Napoli. Napoli's season was good, finishing second behind Juventus, which is a structured team whose value is known.
"(Carlo) Ancelotti's real project will be seen next season. David's agents are waiting for Napoli to resolve the contractual situation to ensure that his future is stabilised."
