Lennon insisted that he hoped to keep Rogic at the Scottish club, as they chase a ninth straight title.

"I haven’t heard anything and there have been no enquiries. It’s just speculation at the moment, as far as I’m concerned," Lennon told the Daily Record.

“He is a good player and I want to keep all of my good players. He’s not fit yet, but, hopefully, he’ll join the group at some stage next week.”

Rogic has been absent from Celtic's pre-season training camp and will miss the UEFA Champions League qualifier against Sarajevo next week.

The 26-year-old has also been linked to Premier League, with Leicester City and Southampton rumored to be interested.

It has been reported that Rogic prefers a move to England, but could be tempted by a lucrative Russian Premier League contract.

The attacking midfielder joined Celtic from the A-League's Central Coast Mariners in 2013.

He's scored 23 goals in 101 matches for the Bhoys - winning four league titles, four Scottish cups and three league Cups.
