Crystal Palace have turned down a massive proposal from Nottingham Forest for goalkeeper Dean Henderson, sources tell Football Insider.
The Eagles maintain that the 29-year-old is strictly off-limits before the September 1 transfer deadline. Forest manager Oliver Glasner was eager to bring his former keeper to the City Ground, but Palace intend to keep the England international at Selhurst Park to protect the core of manager Pierre Sage’s squad.
Henderson, who has two years left on his current contract, proved vital last season. He made 52 appearances across all competitions and captained Palace to a UEFA Conference League title. Over the past two years, he has helped the club secure the FA Cup, the Community Shield, and European silverware. Although Tottenham also monitored Henderson earlier in the summer, Palace have consistently viewed their primary goalkeeper and captain as untouchable.

Sage remains firm on holding onto key figures, especially after defender Maxence Lacroix departed for Chelsea.
Daniel Munoz Set for Nottingham Forest Switch
While Palace are holding the line on Henderson, they have agreed to let right-back Daniel Munoz join Forest.
Football Insider reports that Palace accepted a bid exceeding £22 million for the 30-year-old Colombian. Munoz was rested during Palace’s recent 4-1 loss to Manchester City to avoid injury and is cleared to travel for medical tests.
Unlike the situation with Henderson, Palace officials feel comfortable letting Munoz move on to rejoin Glasner. The club already bolstered their defensive depth by bringing in Oscar Mingueza and Anan Khalaili earlier in the transfer window.
