You do know the meaning of "sell" right? I don't consider those leaving on a free as selling because we don't get anything in return but that doesn't mean I don't agree with them leaving.
Pedro, Giroud and most likely Caballero will leave on a free. Willian is 70-30, for me, to leave at the moment. Won't be surprised if the board end up offering him a 2 + 1 contract extension or something like that.
We will very likely sell one of the left backs to make space for a new one but that aside, the rest is up in the air, a wishlist only. Plus, we don't have exactly a bottomless budget to spend big money on new players to replace all outgoings in one transfer window and if we don't qualify for the Champions League, the budget becomes even smaller than if we qualify for the Champions League, which will impact our ins and outs.
