BBC are reporting it, so that's surely as close to 100% without the club confirming it.

I don't hate van Gaal like Kiko and the majority of redcafe, so I'm glad he's going out on a high. But he hasn't really done enough this season to keep his job, so I think it's the right decision. We really should've gone for Jose after Fergie retired, but here we are 3 years later.

So, success or not?
