What big football transfers could we see this summer?

Football clubs have two transfer windows per season: one from July to August and another in January.

But that doesn't stop the constant flow of rumours throughout the year. For some fans, knowing which players their club will sign next is just as important as the on-pitch results.

Jonathan Johnson, soccer correspondent for CBS Sports, explains, "Fans have a desire to know what's happening at their club on a day-to-day basis. This demand has grown to the point where there's a lot of pressure on people to provide scoops. Transfers have become a measure of success, alongside on-pitch performance. If your club beats a rival to sign a certain player, it comes with the prestige of having spent more money than someone else."

There are two common types of transfers in football. First, when a player's contract with their current club expires, they become a free agent and can join any club without a transfer fee. This is appealing to potential suitors. Second, there are blockbuster transfers where clubs pay a significant amount to release a player from their contract. Some players, especially young stars, have a "release clause" in their contract, which allows negotiation of personal terms if a bid meets a specific sum.

Once a transfer fee and personal contract are agreed upon, the player undergoes a medical examination to ensure they are physically fit to play for their new club. After completion, the player signs the contract, and the club unveils their new signing to the world.

In the past five years, we have witnessed exorbitant transfer fees, leading to an inflation of the transfer market compared to a decade ago. In 2016, Manchester United signed midfielder Paul Pogba for a then-world record €90 million fee, only for him to leave
