Lampard is the obvious choice. You need someone who demands respect in a dressing room in modern football. People's concerns are because he couldn't get about 8 new players to gel during a season where there were no fans and it wasn't proper football. He got top 4 with a team of young players during a transfer ban, in a season of actual football. Last season doesn't concern me at all, especially since Tuchel (who is an elite manager) straight away asked for an upgrade on the forward that Lampard had to use.
It would be a long term rebuild but at least he is someone shown to be willing to invest time and improve younger players. There are no shortcuts and there probably never were. Our only chance is signing young players and making them better, and also developing our own. That won't happen under an outdated, inept manager who is obsessed with experience.
