Oh yeah I mean if I was Ødegaard's agent i'd be telling him to ask for a move back to Sociedad, but i'm a selfish Arsenal fan so I wanna see him here. Anyway it's not like we're doing anything major this January, why not ask for a 6 month loan and see if he's interested, maybe he wants to experience English football.
Loan with low fee and no obligation but option to buy would be okay, I guess. At worst he'll have no impact at all and go down as Denis Suarez mk2.
Think in the summer from a longterm perspective someone proven in his best years would make much more sense, though. Buendia, Sabitzer, Luis Alberto. Someone who can instantly deliver, is a bit versatile and will neither right now nor longterm block ESR's gametime and development. Which is why imo Sabitzer - who's rumoured to be looking to finally leave Leipzig for an abroad challenge - is an almost perfect fit: AM, CM, RW, prime age, captain of his current team, even a bit of an aggressive strain in him, used to physical play due to his Red Bull "upbringing" where everyone needs to put in a defensive shift.
