[4] During January 2019 transfer window, West Ham was also cited as a contender for his services,[5] but it was dropped as Manuel Pellegrini did not consider altering the squad during the season.

[6] On 5 June 2019, whilst preparing with the national team for a double fixture against Jordan and Azerbaijan, Hrošovský was said to almost complete his transfer to Genk.

Verbal agreement was reached despite issues arising, as Viktoria agreed to let him leave during the summer transfer period to help the club qualify to the Champions League group stage.

Genk was said to oppose this arrangement, but the transfer was more than an agreement, as Plzeň agreed with Wolverhampton Wanderers on a two-year loan with an option to buy.

[11] On top of that, Hrošovský made sole seasonal appearance in the Croky Cup in a Round of 16 loss against Royal Antwerp.

In a league fixture against Charleroi, he had beaten Nicolas Penneteau with a back-heel goal in the 39th minute, utilising a pass from Junya Itō.
