Despite having been a French teacher in the dim and distant past, I've taken the easy option with Google Translate:
"While several clubs were interested in Pierre Sage, the RC Lens coach will indeed join Crystal Palace, and everything will speed up in the coming hours, according to our information.
The Pierre Sage saga is coming to an end. Indeed, the RC Lens coach has decided to leave the Artois club after a historic season marked by second place in Ligue 1 and a victory in the Coupe de France.
The destination is now confirmed: Crystal Palace, while other clubs, notably in the Middle East, were interested. The London club, looking for a successor to Oliver Glasner, has made the French coach its priority in recent days. Discussions between the two parties have progressed considerably, and an agreement on personal terms has already been reached, according to our information."
Hopefully, an announcement is imminent if personal terms have indeed been agreed.
