Im intrigued by how football contracts are governed and under which rules and legislation etc.
Im under contract with my employers, if i choose to leave I can leave providing I hand in three or four months notice (in reality theyll put me on gardening leave but thats beside the point). A footballer can he not talk to other clubs being under contract, if so why? Unless of course it is stated within the contract.
I actually did this (football contracts) as my dissertation at uni (I studied law). Bearing in mind I graduated in 2005 (a long time ago), in addition to standard employment laws, football staff are governed by a set of rules imposed by FIFA, UEFA, The FA, PFA and numerous other sporting governing bodies.
So in our case we have employment legislation governing the employment contracts, many of which are EU directives that have been consolidated within English law by Acts of Parliament.
But you also have the football governing body bodies rules, i.e. "if you want to be a member of FIFA/UEFA/The FA and play in FIFA/UEFA/FA competitions, you have to abide by these rules".
These rules are technically legally binding as they are contractual in nature, however they are open to legal challenge where they infringe, for example, overriding principles of the European treaties, such as freedom of movement for workers.
This is what the Bosman case was all about, where there was a successful argument that a club imposing a transfer fee for a player out of contract amounted to a breach of freedom of movement for workers.
The interesting question was where a player requests a transfer that is denied by his club (i.e. our denial of Modric of his move to Chelsea), does this breach freedom of movement principles?
Well technically it does, it also breaches old principles of English employment legislation, but the European Commission which was investigating this exact issue in the early 2000's bottled it and agreed to ratify a new set of transfer rules (which as far as I am aware amount to the existing transfer rules currently in force in FIFA regulated competitions), which included the introduction of the transfer windows, a set of 'compensation' rules for players under 24 and a raft of other changes.
This was to prevent a threatened legal challenge by the European Commission into the transfer system, so overall my conclusions at the time were that while technically still open to challenge, I doubt whether there will be another successful legal challenge to the transfer rules following Bosman as there is no desire really by the European Commission or any other legal entity to interfere in Sport where there are no major concerns that workers are being mistreated and that the football governing bodies are seen to be taking their own action where mistreatment is evident (i.e. bringing in regulations to prevent the transfer of minors across borders etc)
