Both are close to finalizing deals that will see them leave the club before the Sept 2 European transfer window deadline.
Ghezzal will head out on a loan deal, while Diabate may also exit in similar fashion.
The former is a target for Olympiakos. They hope to have Ghezzal signed in the coming days.
Meanwhile, Dijon want to sign Diabate. They want a straight loan, while Leicester want an obligation to buy in the deal.
The news comes from Sky Sports, with the source reporting that neither winger has a first team future at Leicester under Brendan Rodgers.
