Even if VVD is out, we can still win the title. I'd expect us to probably be more like Liverpool of old in that we score a ton, but concede lots too, which to be fair, we have been doing even with VVD.
Without him, our defence isn't elite, but everywhere else on the pitch is. And that's still good enough to challenge for everything.
On the brightside, if we do win the league and/or CL, or get close - nobody can cry that we got lucky with injuries or VAR anymore after yesterday.
