Celtic striker Chris Sutton is exercising his right to speak to other clubs, according to his agent Tony McGill.
Portsmouth and Everton have both been linked with the 32-year-old whose contract at Celtic Park runs out at the end of the season.
McGill insists he is simply carrying out his normal duties on behalf of his client.
He said: 'Chris has a right to speak to other clubs and I'm travelling round speaking to interested clubs at the moment.
'I'm just doing my job and if a club calls me then I will hear what they have to say.
'I won't say which clubs are in the frame but there are more than two clubs interested and they are all in the Premiership.
'They are a mixture of top clubs, middle-ranking clubs and others.
'I really don't know what will happen at the moment, there has nothing been decided either way.
'Chris could sign a pre-contract at one club and play out the rest of his contract at Celtic.
'That's within the FIFA rules and we haven't ruled that possibility out.
'But you never know what can happen, things change so quickly in football.'
McGill jokingly summed up the extent of the interest in Sutton.
He said: 'The way things are going at the moment I wouldn't be surprised if Alex McLeish game me a call - well, to be honest, I would.'
