Due to the financial hardships caused by COVID-19, this year's summer transfer window looks much different than in previous years. Transfer windows across Europe have been widely staggered because of the various ending dates of major leagues. The Ligue 1 window has been open for weeks, while the Serie A window doesn't start until September 1.
Furthermore, since revenue is down, many clubs are treading lightly in the spending department. Teams are relying more on free transfers and cheap signings to boost the quality of their squad while staying financially frugal.
