I think in the short term we need to go back to getting young, hungry lads on an upward trajectory who still have a bit to prove. Maybe even a few who've been cast off by other 'big' clubs.
Bobby, Mane (who was the real start of it all), Salah, Wijnaldum, Robbo, Fabinho.
Then along the way you try to add a couple of proper stars - your Van Dijks (though even he still hadn't stuff to prove) and Allison's.
Easier said than done of course and I reckon we're looking at minimum two years before we have the basis of a really good side again. But we're also probably in an era where you don't need to be really good to win the league so who knows, three good buys, a bit of luck with injuries and better management and we really should be miles better straight away.
