Rensch (Lelystad, 18 January 2003) has been part of Ajax's youth academy since 2016. The Dutch international made his debut for the first team on November 28, 2020 in the match FC Emmen – Ajax (0-5). In total, he played 156 official matches for Ajax's first team, scoring 10 goals.
During his time at Ajax, Rensch won the Eredivisie title twice (2021 and 2022) and lifted the KNVB Cup once (2021). In 2020, he was awarded the Abdelhak Nouri Trophy as the most promising talent in Ajax's youth academy.
Technical director Alex Kroes said: "It was not an easy decision to let Devyne go at this time. As a homegrown player and an undisputed starter, we will certainly miss him here. He was eager to take on this new challenge, and now he has the opportunity to showcase his qualities in one of Europe's finest leagues. We have wished Devyne all the best and hope he will be just as successful in Italy as he has been here at Ajax."
