In the first half of his second season with the club, he continued to serve as a back-up to Donnarumma, and only made once appearance for the team, which came in a 2–1 away win over Genoa in Serie A on 5 October 2019; during the match, Reina was at fault for the opening goal, as he had misjudged Lasse Schone's free kick, but he later saved a penalty against the same opponent, which he himself had conceded, in stoppage time.
