I think you'll find it difficult to find a quote in my posts where I've guaranteed it. I am confident we'll come up at the first time of asking though.
No, it's not rosy, we've been relegated from the top flight for the second time in 7 years because the owner has mismanaged us for pretty much the entirety of his tenure. We're still not producing a decent number of young players through the academy. I don't trust the owner to support the manager as he's promised because he's proven (by a court of law) to be a Big Billy Bullshitter
But Wijnaldum's exit is neither unexpected nor disastrous.
That's partly braggadocio, partly confidence, but I don't think it's as laughable as Leicester fans thinking they can win the league next year or, say, some of your more exuberant fans predicting a top half finish.
Not sure I've seen any evidence that they are. That might be an exaggeration or at worst, a fabrication.
