Celtic manager Neil Lennon has confirmed goalkeeper Lukasz Zaluska has been offered a new contract to stay at Parkhead.
The 29-year old is currently back-up to Fraser Forster at Celtic and is believed to be looking for regular first-team football elsewhere.
Lennon is waiting for Zaluska to make his decision, but the Hoops boss has indicated the club are keeping their options open as well.
"We've made him an offer and he is going to let us know but we are always looking to strengthen our squad," said Lennon.
Hearts keeper Marian Kello has been mooted as one target for Lennon should Zaluska decide against signing an extension.
Zaluska has made 31 appearances for Celtic since joining the club from SPL rivals Dundee United in 2009.
