With the Financial Fair Play rules now in place, many clubs are looking for bargains when it comes to signing players. This is why they will be checking on who is available on a free transfer at the end of the season.
In January, players who are fast approaching the possibility of becoming a free agent at the end of the season, can speak with other clubs about a potential future deal after the expiration of their current contract. With that being said, here is a full free agent XI.
A goalkeeper of the highest quality that is available for nothing. Valdes is currently working his way back up to full fitness after tearing his anterior cruciate ligament in his right knee earlier this year. Before being injured he already confirmed his desire to leave and their will be many suitors for his signature soon.
The Spaniard won every single title with Barcelona and Spain, breaking many records in the process, including failing to concede a goal in 466 minutes in Europe. With a CV as good as Valdes', it won't be long till we see the shot-stopper back in football.
Alves could follow his former team-mate Valdes out of the Nou Camp as his contract at Barcelona is close to expiring. He was previously quoted saying that he will move to England next year, however those quotes are rumoured to be intended to fuel contract talks for Alves to stay.
The Brazilian has been a regular for Barca, playing a major part in the league leaders keeping clean sheets in the first seven games. Alves has won every trophy and despite being 32, is still an attractive option for any team.
The Dutchman and Aston Villa captain is a true leader on the pitch and is as committed as a defender as you'll ever see. His current club, Aston Villa, are trying to tie him down to an extension but their is reported interest from Manchester United, who are managed by Vlaar's former national coach, Louis van Gaal.
Vlaar was the subject of a lot of praise in the summer after his fine performances in the World Cup for his country, the Netherlands. His international experience and leadership qualities will mean he won't struggle finding a new club.
At 22 years of age, Fabian Schar has a big career ahead of him. The young centre-back is extremely highly-rated and made his international debut for Switzerland at the age of just 21.
Schar currently plays for FC Basel and has really impressed during his time there. With interest from Arsenal in the summer, their is no doubt that the people who have watched him will be eager for him to get a big move in order to fulfill his potential.
A complete surprise to many, but one of the best defenders in world football, Giorgio Chiellini is available for a free transfers at the end of the season as it stands. The Italian who has been dominating Serie A with Juventus for many years now and is arguably the best defender in Serie A right now and for Italy.
Chiellini has now turned 30 but has shown no signs of ageing, consistently playing 30+ games every season. He can play left-back too and his qualities are known all around the world which means not only will he have many teams chasing him, but Juventus are making a bad decision if they are willing to let him go for free.
Perhaps the most coveted free agent in the summer of 2015? Sami Khedira, the man who won the Champions League with Real Madrid and then the World Cup with Germany in a matter of months is unwilling to sign a new deal with the European Champions.
The German wanted to leave with now Manchester United player Angel Di Maria but Madrid didn't want to lose both players, leaving Khedira the unlucky one. Khedira is a classy midfielder who is dominant in the air, strong in tackling and doesn't lack goals either for a defensive midfielder. The only barrier preventing him from securing a move away are his high wages, reportedly around £150,000 a week.
Nigel De Jong
As well as Ron Vlaar, Nigel De Jong is also another Dutchman who was not only praised for his performances at the World Cup, but was linked with Man Utd during the summer. De Jong has matured into a reliable player, protecting the back four with tenacity and channelled aggression.
The former Man City player has played a key role in AC Milan's revival in Serie A this season and would be a key miss for them if he were to leave.
Milner is someone who could very well stay at the Premier League Champions but he has been really vocal in saying that he will only stay if he is given a fair chance. Since Nasri's injury for City, Milner has come in and performed extremely well, both attacking and defensively.
He put in strong displays against Chelsea and Aston Villa in recent weeks. Milner is the type of player that will always give 110% for the team and this alone will mean managers will be lining up a deal for the 28-year old.
The Ghana international, who is still only 24, is one of the brightest and upcoming talents in Europe at the moment. Ayew is currently playing for Marsielle, helping them lead the table by five points, seven clear of PSG.
A former Ghana player of the year winner, he has over 50 caps at international level, despite his age. At 24, their is all the expectation that the future is bright for Andre Ayew.
Klaas Jan Huntelaar
There is one thing that Klaas Jan Huntelaar is known for more than anything. Finishing. The Dutchman is known as one of the most clinical strikers in world football which may come as a surprise to many when they realise that he could leave on a free in the summer.
With a sensational record for Schalke and Holland, Huntelaar has shown this season that he clearly still has plenty to offer scoring in both of Schalke's Champions League games, including at Stamford Bridge against Chelsea.
Many years ago, Alexandre Pato was touted as the "next big thing." Whilst it was clear that that the talent was there for the former AC Milan striker, the Brazilian was horribly unlucky with countless long-term injuries.
Pato returned home to Brazil to play for Corinthians before being loaned out to Sao Paulo where he has scored 9 goals in 20 appearances, something Pato is clearly capable of improving on. Since being back in Brazil, Pato has escaped any major injury and has another chance at the end of his contract. Still only 25, this could be Alexandre Pato's best chance in 2015.
