I was going to say that, but we don't know what his existing charitable commitments are (if any).
Is it still (or was it ever!) common practice for clubs to pay players who are set up as companies (offering services of football) so that they pay corporation tax (circa 28%) instead of top rate tax?
Aye, suppose. The old "I do a lot of work for charidee, don't like to take about it though".
