The transfer window does not open up for several months, yet that never causes transfer rumors to cease from existing. Many rumors are ridiculous, while there are some other pieces of speculation that turn out to be completely true.
Through all of this, we see that the transfer market has a major impact on how clubs can either succeed or fail. In today's game, there are plenty of moves that could happen that would cause football to change dramatically.
Here are 10 transfers rumors that, if they turn out to be true, could change football dramatically.
It appears that Michael Ballack may leave Bayer Leverkusen after the conclusion of the season and make a move to MLS.
According to Goal.com, Ballack will be trying to move to five MLS clubs during this summer.
How it will change the game: Ballack moving to MLS would add another experienced player to the league. It also would reinforce the notion that players are still more likely to move to MLS instead of China or the Middle East to close out their careers.
Christian Eriksen is another young player who may make a move to England this summer. Right now, it appears that Eriksen might make a move to Old Trafford after the season ends.
Eriksen still has another chance to impress Manchester United during this Thursday's Europa League match in England.
How it will change the game: Eriksen's arrival would not only mean the arrival of another talented young individual, but it also means that United's youth movement will have Eriksen and Thomas Cleverely holding midfield positions for many years to come.
He is only 19 years old, yet Mario Goetze is one of the most pursued German players in the Bundesliga today. There is a strong chance he could leave Borussia Dortmund this summer.
Goetze will be starring on a German squad that is expected to win Euro 2012 and will probably make a high-profile move this summer.
How it will change the game: Goetze leaving will mean another young German player leaving in order to play in another European nation. This will only help the German squad due to the increased diversity of different European games getting merged to form a master team.
Dortmund will also lose one of their most highly-touted players in their history, though it looks like they will win consecutive Bundesliga titles this season.
Wesley Sneijder is one of the top midfielders in the world and has been heavily linked to Manchester United since his premier performance in the 2010 World Cup.
These rumors have never seemed to stop and will probably never stop until Sneijder joins Manchester United or retires.
How it will change the game: If Sneijder were to join Manchester United, the Red Devils would see their midfield performance go up for several years.
However, Sneijder's age will prevent him from being a dominant player for a long stretch of time.
Eden Hazard is the most highly-pursued young player in Europe and has been linked heavily to Tottenham Hotspur in the last week.
Of course, Hazard didn't leave in the winter transfer window and probably will move from Lille this summer.
How it will change the game: The Hazard sweepstakes will be over, but it will mean that the Premier League will be a center that contains many of Europe's best young players, including Jack Wilshire, Mario Balotelli and Hazard.
It also will cause the Premier League to start moving toward becoming a much more technical league instead of the physical league that it currently is.
There were some bizarre rumors that Wayne Rooney was going to leave Manchester United during the winter transfer window, rumors that clearly did not happen.
How it will change the game: If Rooney left United, the Red Devils would have lost one of their best players and would have caused transfer prices to escalate due to the ridiculous price that would have been warranted for Rooney's service.
Carlos Tevez has wanted to leave Manchester City for over a year now, yet Tevez has not left Eastlands to go elsewhere.
Tevez will probably play for Man City in the coming weeks and will attempt to move to a friendlier environment in the summer.
How it will change the game: The Carlos Tevez transfer rumors will finally end and both Manchester City and Tevez will get to grow stronger from this cancerous relationship.
He has been the best player in the Premier League this season, yet there are rumors that Arsenal's striker Robin van Persie could leave the Gunners this summer for Real Madrid.
How it will change the game: Arsenal have been abysmal this season and look like they are on the verge of getting knocked out the Champions League, the only competition that the Gunners have any chance of winning (though they probably will not advance).
If Van Persie leaves, Arsenal will not even have a chance of finishing anywhere near the top four and will be a mid-table club, a far cry from the numerous titles that Arsenal and their fans expect to achieve every season.
Nemanja Vidic is not going to play again this year after a horrific knee injury, yet the Serbian defender was in transfer rumors that saw Man United's captain getting sent to cash-rich Russian side Anzhi Makhachkala.
Anzhi had already captured Samuel Eto'o earlier in that same transfer window in their quest to become a European giant.
How it will change the game: Vidic's departure would have opened the door for more players to move to the RPL due to the fact that one of the world's best players is moving to their league.
This would also hurt United's defense for the immediate future. Rio Ferdinand is at the end of his career and United's young defenders are still in a state of transition when it comes to developing their future form.
Neymar is one of the top players in the world who is not playing in Europe, and it has been rumored that the young Brazilian could make a move to Barcelona during this summer.
Neymar has been with Santos during the last several years and is poised to be a star at the 2014 World Cup.
How it will change the game: If Neymar were to leave for Barca, the Catalan side would get another fantastic player, which would only help to further enhance their club.
It would also hurt non-European leagues to see a superstar like Neymar leave, which only further enhances the importance of European football for foreign players.
