Q So who is telling the truth? Do Liverpool have to sell Luis Suárez because they have received an offer in excess of £40m or is that figure simply a trigger to begin, or merely consider, negotiating?

A We have not seen the contract so we are speculating and we do not know how much posturing is going on, possibly from both sides, but it is possible that it could contain a clause which is not legally enforceable. As players are such valuable assets, clubs really need to use specialist sports lawyers and Liverpool may well have done so but, equally, there have been cases of club secretaries drafting clauses at 11 o'clock at night that turn out to be not legally enforceable. Such clauses will not stand up in court.

What about the verbal assurances that Suárez believes he received from Liverpool, agreeing to let him leave if someone offered more than £40m?

Any such assurances are legally irrelevant as Premier League contracts contain something called an "entire agreement" clause which excludes, or overrides, all prior verbal agreements. Morally it is a different matter, of course.

Could things have literally become lost in translation?

If Suárez was relying on advice given in Spanish while Liverpool were working in English, it is not impossible that there has been a misunderstanding although, if specialist lawyers were employed, there should not have been.

Are these types of clauses common?

No, not in England. They are rare here – Demba Ba reportedly had one at Newcastle before joining Chelsea – but it is very different in Spain where every player has to have a buy-out clause in his contract.

Can Luis Suárez force his way out by submitting a transfer request?

It would not make any difference. The press always make a big thing of players potentially submitting transfer requests but they actually are a non-factor in football. In Suárez's case it all depends on a specific clause in his contract but generally, if a player is under contract, it is up to the club whether they sell or keep him. If a transfer request is issued, a player might lose part of a signing-on fee – these are usually paid in annual instalments – but, in the wider scheme of things, the amount of money forfeited would be relatively small and cancelled out by the financial benefits of being transferred.

So is talking to the press and telling a journalist you want to leave a more effective tool than a transfer request?

Yes, the interview Luis Suárez has given to the Guardian is a more devastating tool than any transfer request. Wayne Rooney and Gareth Bale may also find doing similar interviews to be much more effectiveweapons.

Could this end up being decided by a Premier League tribunal?

Yes, possibly. Premier League standard form contracts make provision for dispute resolution by the Premier League board and then, potentially, by an independent panel.

Do you think Luis Suárez will end up an Arsenal player?

Yes. Although in some ways players have fewer rights than the majority of employees, they do possess a lot of power – and particularly after the Bosman ruling. If a player makes it clear he wants to leave, there is little point in clubs holding on to someone who may, potentially, begin performing badly. In such instances it's better to cash in.
