It's why the recruitment has to focus on players with potential but who can contribute now also.
Different era - but look at the 84-88 side and how it was built, think people forget how young on average that side was - and how by and large unproven a lot of it was when it arrived (the proven parts all had huge ? Marks against them too like Gray and Reid)
Need to take a few risks on proven talent whose lost its way like Dele, veterans with the right attitude like Tarkowski, and supplement that with younger hungrier players (Gordon, Gallacher, KLP, Braithwaite etc)
