Nah, that's untrue really. It's a message that Arteta achieved KSE's goals for the club this season. Combining it with Eidevall's extension is a reminder they claim to be thinking holistically, and the timing makes sense from their perspective because it erases the uncertainty that would arise—either way—if delayed until the top four situation was determined.
I'm not sure if I'm happy about Arteta being extended, though it has seemed inevitable, but the KSE logic has been transparent and consistent, and I'm happy about that part.
