Look Rich mate, I appreciate I'm on an Everton forum talking to Everton fans, so I don't want to overreach my welcome here. And I say this with the upmost of respect, as someone who really likes your club (and someone who values proper football discussion). But I ask you have some respect for my club here.
I get exactly where you're coming from, you're a a Premier League stalwart with a glorious history and a new stadium. But this is a lad who has risen through the leagues with us from League One, who by all accounts is still in Ibiza celebrating with ten of his teammates in a team that is apparently more together then anyone has seen in recent Sunderland memory, a lad who was scouted and given his chance at Sunderland from the League of Northern Ireland, a lad who will probably play in a stadium that will have near enough a 46k average next season & a club with a fairly impressive history itself (not your levels of course).
Most importantly though we're a club with 100m+ in the bank, a billionaire owner ourselves, and apparently we have more headroom for spending then yourself or many others according to Kieran Maguire the football finance expert -

Yes we're heading back down, but I'd wager he'd quite fancy staying at a club he's settled at, with a manager/ team he likes, and if we fail he'll be off then - like most others who are promoted. If I'm wrong I will hold my hands up of course.
