What he actually said was: "After seven intense and emotional years, I think it's a good idea to let the numerous memories settle in before I take on a new challenge with my team refreshed and motivated."
"I'm going to take a break until further notice."
JK never said anything about a year long sabbatical. The statement was quite vague to say the least, and open to interpretation. So, If he was really set on taking a year out then he would have made it very clear. Basically, he's not got a job right now, so there's nothing else for him to do, so he's taking a break anyway. Right now, he's not received any offers that would turn his head, so the only thing he can do is chill for a couple of weeks and see what turns up.....hopefully FSG on hands and knees.....
It has to be said though, he was expected to take over the reins at Arsenal, but Wenger decided to stay on as manager.
