3. Continuity and confidence
There are objective arguments to support the previous point, but if we want to see it as a subjective issue in which everyone has their own preferences, that's fine. This point stands independently of the above; Returning to the dynamic of putting two top-level goalkeepers to compete for the starting position would undermine the confidence of both, and the continuity of the PSG project.
Gianluigi Donnarumma has been a starter in Paris for a season and a half, without considering the start of this campaign. Putting him back in competition with Navas would be a setback for the trust gained in recent months. And the same would happen with Keylor himself.
Our interpretation is not a preference for the Italian just because, on the part of Luis Enrique, but a way of giving continuity to a project that is intended to be built over time, for the long term.
We must conclude by adding that according to the Spanish newspaper AS, the three-time Champions League-winning goalkeeper is seen as “an exemplary figure” in the Parisian team, and his experience is expected to be “invaluable in crucial moments” for PSG as the season progresses.
