flobaba Lol - That means he will play. 100%
Maybe I'm reading too much into Arteta's words. Think I remember him saying Saka was in contention against City, then missed out completely. Might have done the same with Partey and ESR at one point as well from what I remember, after which they ended up missing big chunks.
But yeah, normally I'd say that means the player is there or thereabouts and we're just playing mind games regarding his availability to fool the opponents.
