Crystal Palace chiefs are torn over who should succeed the departing Roy Hodgson as manager, Football Insider understands.
But a Palace source has told Football Insider that director of football Dougie Freedman is strongly pressing the claims of Barnsley boss Valerian Ismael.
Parish is ready to finalise an agreement with ex-Chelsea manager Lampard who he believes can deliver an attacking approach missing under Hodgson.
However, the Ismael twist threatens to derail that plan in a growing boardroom battle.
It is no surprise to see Ismael attracting the attention of a top-flight club given his recent achievements with Barnsley.
The South Yorkshire side finished 5th in the Championship and are currently at the halfway point of a playoff semi-final battle with Swansea City.
A 1-0 defeat at home in the first leg makes Ismael’s task more difficult going into the second stage of the tie on Saturday.
But regardless of the outcome, this season has been an unqualified success for the 45-year-old manager.
Barnsley escaped relegation to the third-tier by a single point last season, a 91st-minute goal against high-flying Brentford ultimately keeping them up.
Ismael was briefly a player at Palace, making 13 appearances in their 1997-98 Premier League campaign.
The Frenchman later enjoyed spells with Lens, Werder Bremen and Bayern Munich among others.
His managerial career has seen him take charge of FC Nurnberg and Wolfsburg in Germany, as well as stretches in the Mediterranean with Lask and Apollon Smyrnis.
He joined Barnsley in October 2020.
