The Ivory Coast international joined Palace on a six-month loan in January and is now expected to report back for pre-season under Unai Emery, where he will compete for minutes in a crowded Villa attack.
Guessand only arrived at Villa Park last summer in a £30m move from Ligue 1 side Nice, but a goalless return from 13 Premier League appearances saw him shipped out on loan in the winter window. He initially impressed at Selhurst Park, offering Oliver Glasner's side a useful attacking option as they juggled Premier League and Conference League commitments through the second half of the campaign.
A prolonged spell out with a knee injury then disrupted his momentum, and Guessand struggled to force his way back into contention, ultimately limited to just 10 minutes off the bench as Crystal Palace lifted the Conference League with a 1-0 win over Rayo Vallecano.
Reports have suggested Guessand was open to making his move to south London permanent, but new manager Pierre Sage has instead chosen to explore alternative attacking targets rather than activate the buy option, with Jean-Philippe Mateta and Jorgen Strand Larsen already established as his central striking options.
The decision leaves Aston Villa facing a fresh headache over the 25-year-old's future. Having only signed him 12 months ago in what was viewed as a significant statement of intent by Emery's recruitment team, the club will be reluctant to let a big-money addition drift into a second consecutive season on the periphery.
Villa are known to have fielded multiple enquiries from other clubs during Guessand's spell away from Villa Park, giving Emery options should the forward fail to force his way into regular contention.
Emery's pre-season schedule will offer an early indication of where Guessand fits into his plans, with the Ivorian set to compete alongside the club's other central attacking options for a starting role. Whether he can finally deliver on the promise that persuaded Villa to spend big last summer, or whether a permanent exit elsewhere becomes the more likely outcome, should become clearer over the coming weeks.
