Celtic manager Neil Lennon is hopeful of getting his first January signing in the coming days.
The Scottish champions have been linked with Slovan Bratislava striker Andraz Sporar and 21-year-old Polish striker Patryk Klimala of Jagiellonia Bialystok.
Lennon is keen to find attacking cover for Odsonne Edouard, with Leigh Griffiths and Bayo having been ruled out for an extended period.
Speaking from his squad's Dubai training camp, Lennon told Celtic TV: "We have had three or four important calls between the staff and the club and obviously patience is the key.
"January is a difficult month to bring players in. Other clubs know that when you are the buying club, agents do as well.

Lennon may also look to bring in a wide player in January, with Scott Sinclair having left to join Preston and Lewis Morgan on the verge of a move to David Beckham's MLS franchise, Inter Miami.
Mikey Johnston and Mohamed Elyounoussi have also been carrying knocks in recent weeks.
Lennon added: "Already a couple of players have left in Scott and Lewis, we might streamline it a little bit more, but across the board we are looking to bring a few players in."
The Celtic boss has also been encouraged by the showing of another two wide players in Dubai.
