Agree with that CD. My interpretation is that Blackie is saying what all the squad are probably thinking and that is: if we put in the work ethic, and with a big name player on board, we can show the board and the fans that we can all deliver and reap the rewards.
I'm sure signings like Marius will boost the gate reciepts, get us higher up the table and better cup runs and, ultimately, boost the funds available to reward all those who put in the effort.
Every player at this club knows that, if they were somewhere else, there will be big differences the earnings of each individual. They also know that the higher earners have to justify what they get and work harder to maintain their place in the team.
