Celtic are keen to extend Tom Rogic's contract, with manager Ronny Deila playing down the prospect of losing the Australian midfielder.
The Norwegian manager was asked about reports linking the 23-year-old with Leeds United.
"I haven't heard so much about that," Deila said. "We want to re-sign Tom Rogic and have him here for the future.
"He has had great progress and we see a lot of potential in him. He needs time and he's going to stay here."
Rogic, capped 13 times for his country, has been a regular in Deila's side this season, scoring six times. He is currently contracted until 2017.
"He can be much better because he's only played for six months and been out for a year [injured] before that," explained Deila.
'We have our targets'
Deila was also asked if Celtic had tried to bring former player and winger Aiden McGeady back to the club on loan from Everton.
"No, we haven't," he responded.
"We have our eyes open all the time. There's nothing concrete. It's a difficult case always with the Premier League players. Everybody knows the standard and the amount of money [involved]. There's nothing new there.
"We are looking all over Europe and of course the Premier League is one of the best, maybe the best league in the world so of course we will look there as well but everybody knows it's a big gap between the Scottish [Premiership] and English Premier League.
"We have our targets. Now it's to get it right. We will do the same thing as last year - get stronger in this window."
Striker Anthony Stokes, who has played just twice for Celtic this season, is expected to go out on loan and Inverness Caledonian Thistle manager John Hughes is keen to sign the forward.
And Deila said of the 27-year-old: "He has some options but together with Stokesy we haven't decided what is the right one yet.
"A lot of clubs have been in contact who want to have Stokesy on their team.
"We will see what Anthony wants and what is best for the club. He wants to get some games under his belt.
"What everybody hopes is that he finds himself, gets some good performances and can then perform for Celtic again.
"He has a contract with the club and Stokesy knows the things he has to take care of.
"Hopefully he will get a good run of games, score some goals and get back in good confidence and the best shape he can be in."
