Guehi came through the academy ranks at Chelsea before completing an £18million move to Palace in the summer of 2021 having found first-team opportunities limited.
The England international is out of contract at the end of next season, which has alerted the Blues to the fact he could be available for a cut-price fee next summer.
Guehi is said to be in no rush to commit to a new deal at Selhurst Park in anticipation of interest from top six clubs in the summer.
The centre-back was wanted by Newcastle after starring for England at the Euros, but the Magpies could not agree a fee with Palace.
Foxes chief takes the reins
Leicester owner Aiyawatt 'Top' Srivaddhanaprabha will take more of a lead role in the club's search for a new manager after being left unimpressed by the appointment of Steve Cooper.

As previously reported by talkSPORT, Top had reservations about hiring former Nottingham Forest boss Cooper right from the start of his tenure, but backed the judgement of long-serving director of football Jon Rudkin.
Top made the decision personally to fire Cooper in the wake of Saturday's 2-1 defeat at home to Chelsea.
And, while not the deciding factor, sources have told talkSPORT he was unimpressed with the 44-year-old's scathing post-match attack on referee Andrew Madley.
The Thai businessman, who consulted senior Leicester players before making his decision to axe Cooper, had Graham Potter top of his wish-list to replace Enzo Maresca last summer but could not get the deal over the line.

Cunha stance revealed amid red-hot streak
Wolves have promised manager Gary O'Neil they will NOT cash in on star man Matheus Cunha in January, according to talkSPORT sources.
Cunha has started the season in sparkling form, scoring seven goals and providing three assists, including a brilliant double in Saturday's 4-1 demolition of Fulham to ease the pressure on O'Neil.
The Brazilian's impressive displays have put him on the radar of clubs
including Manchester United and Tottenham, while he has also been scouted by several top European teams.
Wolves have become a selling club in recent transfer windows and allowed both Pedro Neto and Max Kilman to depart for Chelsea and West Ham respectively in the summer, leaving O'Neil shorthanded heading into a daunting set of early season fixtures.
But director of football Matt Hobbs is understood to have told O'Neil they do not plan to cash in on any more of their prized assets this winter.
O'Neil was fighting to save his job after supporters turned on him following a ten-match winless start to the campaign.
But the hierarchy are more relaxed about his position after back-to-back victories over Southampton and Fulham either side of the international break.
Spurs' emergency deal
Tottenham are considering delving into the market for a new goalkeeper in January amid fears Guglielmo Vicario faces months of the sidelines.
