Sometimes we need to break the bank to fix a problem. Ten years ago we paid 30 mil to get stability in defence for years by buying one of the top defenders in the world. Our midfield has been crying out for a 'Ferdinand-like' long term fix for a long while for instance - 30-40 mil to get that essential player that keeps us at the top level.
That's when I'd like us to pay what it takes - I'm happy with 'value' signings in the main, because we are very good at securing them, but I don't think they should be the only way we get players, as we will end up like Arsenal. The stature of our club dictates that we can spend that much once every two or three years.
I don't think Lucas was a player we needed to spend that much on, but I cannot second guess SAF
