The French striker is the subject of serious interest from Brighton and Hove Albion in England's top flight.
While Celtic have not agreed to sell, Edouard will be hoping for the move to go through.
His captain, however, believes the Frenchman is behaving as a consummate professional throughout the saga.
"Everybody becomes an expert in body language in these situations," said the midfielder, per The Scotsman.
"That's just football. You are under the microscope every single time you walk out on the pitch. Everybody is looking at you and judging you and your body language.
"But all I can say for Odsonne is that he looks as relaxed as ever.
"He is in good spirits. Every time he is around the training ground he is having a laugh and a joke and I think his performances in the last few games have looked right at it.
"He has looked bang at it to me. He is giving defenders problems, he is looking strong, he is looking quick and getting himself into positions where he has goal scoring opportunities. He got one or two in pre-season, and he looks in good form. He seems happy as well."
He added: "I firmly believe that every time you go on the pitch, you give your absolute best.
"In terms of transfers and things, that's in the club's control and, as players, you love playing football and want to enjoy it until something happens. What I will say for Odsonne is that since he has come back he has looked hungry and as long as we can keep him we will be happy."
