The future of Dennis at Turkish club, Istanbul Basaksehir, remains uncertain after the club opted not to secure him on a permanent contract. Dennis had moved to Istanbul Basaksehir on loan from Nottingham Forest in the summer. Despite his efforts, the 26-year-old has struggled to make an impact, having only made eight league appearances without a goal or assist. He has also grappled with injuries since joining the team. With his loan set to conclude next summer, he is expected to return to Nottingham Forest.
