It would look really bad if you can get a player like that for a 'reasonable' transfer fee, and then wouldn't pay him enough. Harry Kane's wages + a London Weighting Allowance maybe.
We can pay decent wages, just not obscene wages £100-170k plus bonuses for the top players, just not £200-£300k.
If we did that too many other players hands would go up saying what about my pay rise.
