Celtic manager Neil Lennon has reiterated his intention to rebuff any approaches for captain Scott Brown during the summer.
Brown is out of contract next summer and the influential midfielder has been linked with a move to English Premier League side Newcastle United.
However, Lennon has confirmed talks regarding a new deal for Brown are ongoing and he is determined to hang on to the Scotland international.
Lennon said: "We opened preliminary talks with Scott at the end of last season.
"He's on record as saying he wants to stay at Celtic and that is something I'm very pleased about.
"I'm hoping to get him tied down.
"I wouldn't be surprised if there's interest as he was magnificent last season.
"I'd be unwilling to sell him and I'd rebuff any offers."
