How much did Mawson cost

[The Swan]

I just wonder how much did Mawson cost. I know he only played one half today but I have not been impressed with him.
Another signing who was injured when he put pen to paper. When I have seen him play I have been very disappointed with him.
I know he is not the only new defender we have signed but he was the main one.
We need c a good old fashion centre half who can head the ball and can tackle and pass to ball to his team mates.

Not much to ask.
