Both England internationals are in demand, with bigger clubs interested in signing them.
Arsenal want to sign Eze, a talented attacking midfielder, while Newcastle and Liverpool are interested in Guehi, a skilled defender.
However, Palace are not willing to sell either player at a low price, and Guehi's contract is set to expire soon.
This means that for now, Palace are prepared to keep both players and allow Guehi to see out his contract.
