There was little doubt that Gianluigi Donnarumma would be Paris Saint-Germain's first-choice goalkeeper eventually, but at least for the 2021/22 season it was expected that Keylor Navas would keep the position, therefore the injury suffered by the Costa Rican has come at the worst possible moment.
Donnarumma is so talented, you don't want to cede your position to him because there is a very real chance you won't get it back.
The Italian stopper will play against Angers and RB Leipzig in the next two matches after Navas had to leave the pitch on as Costa Rica took on the USMNT on Wednesday night with a right adductor ailment, say L'Equipe.
However, the Costa Rican Football Federation reported that the PSG goalkeeper had some hip discomfort. Sports media in the country have reported severe pain in his thigh. That said, the duration and exact issue has not been disclosed yet, pending medical tests in Paris.
If Donnarumma plays well in these two matches, he isn't going to get dropped, it's as simple as that, and this is why Navas will be so disappointed, he can't defend his position whilst injured.
