I too think we should have signed a few more players over the last 3 transfer windows or so.
But on the net spend issue, I think it's a bit unfair. We have sold Coutinho for a lot of money, which skewes the comparison to some other clubs who have a higher net spend than us.
Since 16/17 we have the 6:th highest gross expenditure. City, Chelsea, Manure, Arsenal and Everton are above us.
