Stengs came through the AZ youth system and had three impressive seasons in the Eredivise before he left to join Nice in 2021. However, a year later he was loaned to Royal Antwerp where he did well enough to convince Feyenoord to bring him back to Netherlands. He netted 13 goals and registered seven assists in their 2023-24 Eredivisie title run, but his progress stalled last season as injuries kept him out for most of the campaign.
