It's starting to become a worrying trend.
He's contracted until the end of next season.
Wants to sort out the next contract after that but because it's dragging out it's read as "maybe they don't me, but I don't want to leave but maybe I'll have to leave early".
Sound familiar?
He'll pick up a deal anywhere on really good coin and yes, I understand he wants to sort out his future but there's potentially another year to sort that out and for his value to go up.
If he really doesn't want to leave, and they want him to stay ( and they'd be stupid not to ), it'll happen.
From what I've read, he's not one of the players that have been told to look elsewhere.
Maybe they're clearing the decks to re-sign him long term and need to know how much dosh they've got because as a proven SOO player he won't be cheap and there'll be plenty of clubs that will offer more.
