Drommel made 66 appearances for PSV, winning two league titles and a KNVB Cup. However, he had hoped for more playing time. The arrival of Peter Bosz did not change his situation, as Bosz preferred to stick with Walter Benítez in goal. Drommel has fond memories of his time at PSV, including the 2018 KNVB Cup final win over Ajax, where he saved a penalty from Edson Álvarez.

In an interview, Drommel credited fatherhood with making him a better goalkeeper. He also discussed his rivalry with Lars Unnerstall, his admiration for Marc ter Stegen, and his ambitions to play for the Netherlands national team.
