The next few transfer windows are set to look very different than previous years with the financial impacts of coronavirus limiting what most clubs can spend.
Barcelona's vice-president Jordi Cardoner confirmed that many teams will partake in swap deals this summer with several having big squads and high earners they need to get off the books.
The window is likely to be restructured with a mid-August start date and could be open until October to give clubs who are struggling the chance to sell.
Manchester United could dictate a lot of the window, with the club being in a healthy financial position while Manchester City may also have some funds to spend, but significantly less than they have enjoyed previously.
