This illustrates perfectly the folly of these enormous contracted salaries. Bale is guaranteed to be paid £600,000 a week for the next three years. Real Madrid's problem is to find a means to pay that £95 million (or make up the difference if any new club pays him less) while depriving itself of his services.
The only clubs with a realistic chance of bridging that gap for a 30-year old appear to be Chinese.
