Another possible 'swap' deal to watch?

The traditional transfer swap deals are very much a thing of the past in football these days. But what we do see a lot of, is what I call a ‘favour for a favour’ deal.

This is all because of the financial rules around trading and making money in football these days. Clubs will do deals with other clubs and although technically they are separate deals, they are still unofficial swap deals so that they help each other keep within the rules set.
