Just after the match the other day a good friend of mine that works in production at NBC here in the states just causally mentioned our 'troubled locker room' as if I could expand upon it. It wasn't a surprise but I obviously don't have any details. He's a neutral that just loves football, and sound engineering! But his supplemental evidence was what he heard an analyst saying off camera (could be anything and anyone, I know) but also Martinez on set not too long ago also saying things to that effect.
So that's not a clear explanation for anything, but it was information from someone who isn'tt really all that invested in Everton and thought he was spouting common knowledge to someone.
