Crystal Palace are poised to appoint Pierre Sage as Oliver Glasner’s successor after holding productive talks with the Frenchman.

Sage, who guided Lens to the Coupe de France and second place in Ligue 1 this season, is understood to have agreed terms on a two-year deal with the option of a 12-month extension. Compensation for the 47-year-old must be resolved but that is not thought to be an obstacle.

Palace identified Sage as their primary target after missing out on Andoni Iraola, who joined Liverpool having left Bournemouth. Sage’s preference for a system similar to that employed successfully by Glasner is believed to have been a major factor. He previously had a spell in charge of Lyon after stepping up from the youth team.

Palace are hoping to build on a period of unprecedented success after Glasner led them to three trophies in 12 months that culminated in the Conference League triumph in Leipzig. That earned entry into the Europa League and it was understood there is a boardroom recognition that there will need to be substantial investment in the squad to cope with a second successive season of European football.

In January Glasner revealed his intention to depart after accusing the chair, Steve Parish, of abandoning him and his squad, and Palace hope that moving for Sage can provide stability before a busy summer. Several players including Adam Wharton – who is wanted by Liverpool – are likely to be in demand.

Glasner looks likely to take over at Milan, having rejected an approach from Feyenoord after the sacking of Robin van Persie last week. He held extensive talks with the Italian side last week and is expected to agree a deal to replace Max Allegri, who was dismissed after finishing fifth and qualifying for the Europa League. That raises the intriguing possibility of a reunion with Palace.
