In summer 2014, Cassamá signed with Spanish club CF Reus Deportiu, quickly becoming first choice as well as a fan favourite.[2] He contributed 17 games in his second season – play-offs included – helping the side reach Segunda División for the first time in their 107-year history.[3]
Cassamá started the following campaign with the reserve team in the 1. Liga in order to regain match fitness, returning to the main squad ahead of 2022–23.[11] He made his Super League debut on 13 August, in a 2–2 draw at FC Sion.[12]
Cassamá injured his patella again in October 2022, this time in training.[13] The following 25 May, Grasshoppers announced that his contract would not be extended.[14]
Later career
On 11 August 2024, Cassamá signed for Swiss second-tier club FC Schaffhausen.[15]
