Lennon is resigned to losing the Kenya midfielder this summer.
"The Cardiff deal has fallen through because it wasn’t right, so they will have to come again," Lennon admitted. "Whether they come again or not, I don’t know. Southampton may also come back in again. But I’m sure something else will develop."
Lennon added: "It will be the coup de grace for the club’s signing policy, bringing in the kid for £900,000 and selling him on for £10m-£12m."
