Not a particularly good comparison, comparing footballers to CEOs. For a start, when you talk about multimillion pound salaries for footballers, you only tend to be talking about those footballers playing for the championship/premiership clubs, and any salary comparison ought to be made with TV entertainers, since it is TV money that has fuelled the surge in their salaries. And much of the salary tends to be performance related, much more so than any CEO.
More interestingly, CEO pay has outstripped your average workers pay over the last 3 decades - In the US, CEO pay has risen 725% pm average between the late 70s and now,whilst average pay for employees has risen only around 10% during the same period. We now have ridiculously large and indefensible pay gaps between CEOs and their corporate employee average salary, with CEOs on average earning 200 times more than the average wage at their company, compared to just 30 times more back in the 1980s.
And CEOs have certainly not got that much better at doing their job, at a time when your average employee probably has to do more in their daily job than they ever did with technology -enabling changes and staff layoffs.
CEO and board salary at the major corporations is determined by them, with input from salary analysis firms that always offer comparison with the upper quartile of "similar" companies, ensuring the pay is on an ever upward spiral - and individual shareholders have very little say or power in the salary awards, although that is changing a little bit recently.
Yes, a visionary CEO is worth good money - but for many of them, a salary average 200 or more times the average wage of their corporate employees is difficult to justify, especially when some of the bonus schemes seem designed to shovel additional money into their pockets rather than be a true measure of outstanding performance or exceeding demanding targets.
