The big massive stadium we've just built would be a good start. State of the art and best in the country. The atmosphere and passion of the fans would be another.
After that it's probably going to have to take a (hopefully short term) rebrand of us being a good stepping stone to 'bigger' things like we did with Lukaku and Stones. Like Brighton but as a bigger club where we can say we will get you into the window of the elite teams.
Players aren't going to care about players who were good when their great great grandads were alive when other clubs have had Drogba, Rooney, Shearer, Aguero whilst they were growing up. We need to be pitching that we can get them to that level or at least they will become a cult hero like Richarlison who we turned into Brazils number 9.
It's a pretty tough sell but Moshiri was partly right in that we don't want to become a museum, we need to be looking forwards.
