I’m not sure if you’re examples are applicable to unknown quantities like Tavares. Names you mentioned are fairly known to the point where what their fans base says based on bitterness doesn’t mean anything.
An Arteta/Edu signing being loaned out after 1 season is essentially a kiss of death. Not sure what kind of top player you’re expecting down the line when we’re about to spend £30m+ on a proper proven player replacing him.
