Slegers started her youth career with local Someren side SSE.[3] She subsequently spent time on the books of Arsenal from 2006 to 2007, before returning to her home country to launch her senior career with Willem II.[4] In 2011 Slegers left Willem II for Swedish club Djurgårdens IF.[5] When Djurgårdens were relegated in 2012, she moved to Linköpings FC for the following season.
A serious knee injury sustained in November 2016 eventually brought about the end of Slegers' playing career and she was forced to announce her retirement in February 2018.[6]
Slegers was disappointed when a knee injury ruled her out of UEFA Women's Euro 2017, which the Netherlands hosted and subsequently won. She had previously missed a year and a half of football due to a pelvic injury.[8]
