I won't be surprised if the money dribbles out, as directors fees or dividends, to him over quite a number of years, because his playing career will be much shorter than a normal working life. This may have the effect of reducing his tax bracket, and saving NI. Perhaps his company will diversify into other line of business, such as a Caribean hotel, which the directors will be obliged to visit from time to time.
Company contributions to his pension scheme will be free of income tax, NI and corporation tax.
Even a plumber can do all that.
Professional sportsmen AFAIK still have special rules allowing them to draw their pension quite young, when they're "past it."
