The departure of Bayer's coach, Xabi Alonso, may also impact Grimaldo's future in the Bundesliga. Alonso was instrumental in bringing Grimaldo to the club from Benfica.
Grimaldo, now 29, began his career at Barcelona, where he developed through the club's youth academy, La Masia. He later moved to Benfica before joining Bayer Leverkusen for his second season.
