I agree with that up to a point, the nucleus of the team are young and should benefit greatly from what they have been through over the last couple of seasons. We don't need to sign a whole host of players this year, but must be more selective in the additions we make & it's entirely possible we may have to sacrifice one of our better players to finance the signings we need to make.
We need an experienced centre back possibly a slightly younger version of Boly, though I would like him to be given another year as back up. We clearly need a striker who has half a chance of staying fit, and we also need what we have called in my day a midfield general, & possibly yet another goalkeeper (I don't think Sels is the answer) I reckon add them to the majority of the group we have now should see us stabilised.
I would love to see us have a season where aren't constantly looking over our shoulders, we only need to make marginal gains in the areas where we have been found wanting this season IE defending set pieces, better game management to achieve that, but don't think Nuno is the man to lead us there
