The Dutch midfielder was signed by the Scottish giants in July 1999 but has merely been a squad player during Martin O'Neill's reign with the Hoops, and it is thought that the 29 year old former Feyernoord player Petta would dearly love a move back South of the border to get regular first team football again, however as is in Bolton's case the midfield is already littered with good players and the situation would be the same here for the Dutchman as it would be in Scotland so im not sure of the validity of this speculation.
The main aim is to get a striker in, preferably before next weekend and also a defender, we are well covered in the midfield area.
