Brendan Rodgers insists he has "no fears" over Matt O'Riley leaving the club.
The midfielder has been linked with a move to Italian giants Inter Milan after having a strong start to the season.
But Rodgers was keen to stress the 22-year-old is fully focused on playing for the Scottish champions.
He said: "I don't have any fears over any of the players. I'm delighted for Matt, he's made a fantastic step forward this season as a Celtic player and in his career.
"That shows the focus and mentality from training he's taking into games. He will always attract the interest of teams.
"But I don't have any fear, he's a good guy who works very, very hard. When you do that, you're always going to have interest."
Meanwhile, Celtic have released a statement confirming their stance on the recent European Super League court ruling, ruling out any involvement in the competition.
It comes after the rebel clubs involved won their case at the Court of Justice on Thursday.
And the Scottish champions have reaffirmed their desire to stay within the UEFA framework.
A club statement read: "Celtic Football Club has noted today's judgement delivered by the European Court of Justice.
"The resolution regarding the framework for prior authorization of other competitions refers to outdated UEFA statutes that were already amended in June 2022.
"We must be clear that this does not in any way endorse or approve the so-called 'Super League' project.
"Celtic plays an important, leading role within the European Club Association framework and as a club, we are fully committed to working through the ECA, alongside our fellow European clubs to uphold the values that define European football.
"We can only achieve our objectives through the strong partnership ECA enjoys with UEFA.
"The wider European football community is not supportive of the ESL, and Celtic, like many other clubs, will continue to promote the interests and protection of football’s broader family through the ECA and UEFA."
