Celtic boss Gordon Strachan admits he's keen to re-sign Cameroon defender Jean-Joel Perrier-Doumbe.
Strachan also revealed there has been interest in defender Scott Cuthbert and utility player Adam Virgo. But he maintains the latter is not set to be reunited with his former Brighton manager Mark McGhee at Motherwell.
He said: "There was an enquiry last week about Scott Cuthbert and there has been an enquiry about Adam Virgo - but it wasn't from Motherwell. We are looking into it."
