Neil Lennon is adamant 'everything is above board' regarding Celtic's signing of Lassad Nouioui following a protest from Levante.
Nouioui joined Celtic on a two-year contract over the weekend, but Spanish side Levante subsequently claimed that the Tunisian striker had already signed a deal with them.
Levante stated they would consider reporting the matter to FIFA, but Bhoys boss Lennon is unconcerned about the situation.
"There is nothing really to say," Lennon told Sky Sports News at Parkhead to publicise a cycle ride for former team-mate Stiliyan Petrov in support of leukaemia and Lymphoma research.
"He is a Celtic player who did his medical yesterday and he is training this morning at Lennoxtown with the rest of the players who are here and we are very pleased to have him.
"When the story broke about Levante we were involved in the game (against Hibernian on Saturday) but having spoken to Peter (Lawwell, Celtic chief executive) and his (Lassad's) advisors everything is above board, it is the way we do our business anyway.
"Whether another agent got involved I don't know, sometimes these people do get involved and sort of muddy the water a little bit but as far as we are concerned everything was done the right way.
"I don't know what repercussions there can be, certainly not on our part anyway. I am assuming that the player is aware of the fuss."
