The France midfielder is attempting to force through a move to Valencia.
Spalletti said, “Kondogbia has been very disappointing and his behaviour does not reflect the person we know. He is damaging himself with this behaviour.
“He wants to go to Valencia on loan and save a bit on his wages, but he wants it too easy… When there is something you don't agree on, you find a middle ground. Considering the money spent on him, it's difficult.
“In my view, Kondogbia was given some bad advice, as this sort of attitude is just not part of his personality.
“Kondogbia is strong and has been paid as a strong player, so if there aren't the right conditions for him to go, then he's staying here. We'll evaluate whether to sign someone else in the middle, but I won't let a quality player leave without a quality replacement."
