It is not about being good enough.
The way Wolves play is not a great fit for Gibbs-White.
They have played 343 and 352 without offensive midfielders. Gibbs-White is not a winger and not a striker. And when Wolves have better wingers and better midfielders than Everton, it will be hard to get minutes out of position.
I expect Everton to play 3421 this season. With two "number tens" just behind Calvert-Lewin. Alli, Gordon, Gray and hopefully Gibbs-White compete for minutes. And with 5 subs they should all get minutes.
