That's only true if you isolate this incident though. The truth is he has a history of hinting and teasing fans and using social media to engage with people about the stadium. People think he's doing that again now, but he's stopped engaging with them. Circumstantially, it definitely looks like he's talking about Everton. He might not be, but people aren't being neurotic here, he clearly knows what his comments look like and he's done nothing to dampen the flames. Either it is Everton related, in which case he shouldn't have tweeted it if he wasn't going to clarify, or it isn't and he's just enjoying the attention. Either way, it's not very professional.
