Would be a smart move from Chelsea if they could make it happen. But not sure why Haaland would agree to this, seems like a deal with few benefits and many downsides for him. These kind of deals are usually more attractive to players that feel the need to jump on the opportunity to sign for a big club, because that opportunity may never come again. Haaland knows he can pick and choose next year, and to me it makes little sense to why he would lock up his future next summer already if he is going to stay a year anyway. A lot can happen in a year, Chelsea could miss top4 and Tuchel might be long gone next summer.
