With the January transfer window now open, clubs across Europe will be actively looking to see if they can strengthen their squads in the final months of the season. Whether it's to make a final push for a title or avoid relegation, some teams could be looking to make one or two key deals to get them through.
However, more often than not, the winter market is much quieter than the summer, as most teams plan ahead when they have bigger budgets and players are more affordable and available. However, January also plays a crucial role in some summer business, as it is the time when teams can begin negotiating deals with players in the final six months of their contracts.
The football world undoubtedly saw the high-profile example when Kylian Mbappe made his long-awaited move to Real Madrid after letting his contract expire with Paris Saint-Germain. Los Blancos were free to enter into discussions with the player months before announcing the deal, thanks to the 'Bosman Rule', one of the most influential regulations in modern football history.
Some of the best players in football history changed clubs for free. Here are the biggest free transfers of all time.
The story of Bosman's decision originates from the man named after him, the relatively lesser-known Jean-Marc Bosman. A midfielder from Belgium, Bosman's journey to change the course of football history began in 1990, during his time playing for RFC Liege. After two years with the club, things had not worked out for either side, and with a more lucrative offer from French second division side Dunkirk, Bosman was keen to make the move.
At the time, if a player wanted to leave a club, they needed the club's permission to do so, either on a free transfer or for an agreed transfer fee. Ending a contract to leave for free was not common practice. Bosman made his intentions clear to Liege, but the club refused to let him leave without receiving a fee. The asking price was too high for Dunkirk, leaving Bosman stuck in Liege. To make matters worse, the club responded by withholding 75 percent of his salary due to his attempts to leave.
Frustrated and feeling mistreated, Bosman decided to take his employer to court. After a long legal battle lasting five years, the case was finally settled on 15 December 1995. Bosman's persistence resulted in the introduction of one of the most seismic law changes in football history.
The Bosman decision in 1995 was a landmark, allowing out-of-contract players to move to other clubs without a transfer fee.
Along with his lawyers Luc Misson and Jean-Louis Dupont, Bosman fought the free agent's freedom at the European Court of Justice with his case against Liege. The party argued that the 1957 Treaty of Rome guaranteed freedom of movement for players anywhere in Europe.
Bosman's win meant a law was implemented that when a player's contract expires, they can leave their club on a free transfer, enabling them to negotiate significant signing bonuses and lucrative wages with new teams to compensate the absence of a transfer fee. Similarly, players nearing the end of their contracts could demand higher wages from their current club, which often faced pressure to meet these demands to avoid losing the player without receiving any transfer compensation.
GIVEMESPORT Key Statistics: Edgar Davids and Gianluca Vialli became the first high-profile names to complete Bosman transfers in 1996, less than a year after the rule was introduced.
Since then, there have been numerous examples of players running out of contracts before joining new clubs on free transfers. Steve McManaman became the first prominent English player to use this rule to his advantage when he left Liverpool for Real Madrid in 1999. Just two years later, Sol Campbell made an even more monumental switch, leaving Tottenham for Premier League rivals Arsenal - a move that saw him branded as one of the greatest traitors in football history.
Michael Ballack, Andrea Pirlo and Robert Lewandowski all achieved significant success at their new clubs after completing free transfers. Meanwhile, Lionel Messi shocked the football world by leaving Barcelona after failing to agree a new deal, joining Mbappe and Neymar at PSG. /Telegrafi/
