What I think is acceptable is the clubs choice not to sign anyone and in the same season getting its record points total after 26/27 games without a home advantage.
Would I like to see us sign good quality players? Absolutely but with clubs slapping a ridiculous price on players heads these days I completely understand why we chose not to go for anyone. When I look at the majority of players signed by other clubs, Jorginho, Fred, Richarlison etc and the money it cost I don't think there are many that we could have got that would have genuinely improved us.
We have the HG issue to deal with, we are at our maximum based on nonHG registered players for the Champions League and we got touted a lot of money for not a lot of player it seems (£40m for Grealish or whatever it is is £40m that we can put elsewhere as and when a player comes up)
We've coped very well, it's a long term project and whilst I wouldn't be happy to see it continue like this for the long term I'm very content seeing us keep our head above water when it comes to the best of them all whilst we try to balance the books
