Not writing it off, but willing to sacrifice it if we can get a manager with a long-term plan to build a team around a core group of players who will be the spine of the team for the next 8 years.
We can't go from qualifying campaign to qualifying campaign picking 30-something Championship players and whoever is warming Celtic's bench.
For example, look at our defence. We can build a squad around Kieran Tierney, Andrew Roberston, Scott McKenna, John Souttar, Liam Lindsay and Callum Paterson. Use the next campaign whether it be Nation's League or Euro 2020 qualifying to get them to gel together, and we should see the benefits later. Replicate in all the other positions. As long as we continue to pick players in their late 20's with single digit caps, we'll never progress.
We haven't had a manager with a long-term plan in my living memory. As long as the next campaign is always the priority, we'll always be stuck with the safe option, filling our squads with dross like Russell Martin, Chris Martin, Gordon Greer, etc.
