Full-backs are increasingly recognised for their contributions to successful teams in Europe and throughout the world in the 2020s.

Premier League title-winning managers like Pep Guardiola and Jurgen Klopp have redefined what is expected of the modern wide defender. You need only look at the contributions of the likes of Trent Alexander-Arnold, Andy Robertson and Kyle Walker to see how top sides now rely on unlikely sources of creativity and goal-threat for success in England's top flight.

Full-backs are now seen as marquee signings in the transfer market, with the right player capable of locking down one side of defence and providing width and quality delivery from the flank. But which stars could be on the move this summer, both in the Premier League and further afield?

Here are the best full-backs on the transfer market this summer, both of the left and right persuasion.
