Sven Goran Eriksson is looking to sign a new number one goalkeeper when the transfer window reopens in the New Year, with the Swede unconvinced over Andreas Isaksson, Joe Hart and Kasper Schmeichel.
It is believed the City boss is weighing up a £5million bid for Boruc, who still has two years left on his contract with Celtic and admits he wouldn’t mind penning a new deal at Parkhead.
"I'm waiting for Celtic's directors to make me an offer," said Boruc. "I want to stress I am happy here but things can change quickly in football."
