Its easy to see articles like this and start worrying, but there's other articles written in exactly the same manner but inserting a different managers name. A quick google and you can see similar written about Pochettino, Zidane, Simeone, and Enrique.
Personally I would think if they do sack GP the big club arrogance will kick in and they'll think 'well we're not doing that again'. They'll revert to type and go for a big name manager.
