Sol Campbell has called in players' union chief Gordon Taylor after allegedly being threatened with a five-year gagging order by former club Notts County.

The League Two club will not release Campbell's registration so he can sign for another club until an agreement is reached on a 'statement of departure'.

The 35-year-old former England international is refusing to sign the gagging order as he wants to reveal the truth about his short spell at Meadow Lane and has turned to PFA chief executive Taylor to resolve the situation.

"You often hear the phrase 'nothing surprises me in football'. Well, this has surprised me," said Taylor in the Daily Mail.

"This is different to say the least. It is also very difficult.

"Notts County are holding onto Sol's registration and refusing to release it until he agrees to a five-year gagging order. Clearly, Sol needs to express the real reasons behind his departure, and will not agree to such a gagging order.

"Instead, we are trying to agree a form of words, a statement that both sides are prepared to accept, that will enable Notts County to release Sol from his contract, release his registration and let him make his appeal to the Premier League to find another club before or during the January transfer window."
