Lee Naylor says he is happy to stay at Celtic and is unsure if a possible move to Portsmouth will come to fruition.
The full-back has yet to feature in the SPL this season under Tony Mowbray after losing his place in the side to new signing Daniel Fox.
He was not included in the matchday 18 for Sunday's game at Hibernian and attracted interest from Portsmouth earlier this month.
Naylor is aware of the speculation about his future, but insists he is willing to fight for his place in Celtic manager Mowbray's plans.
"There's been a bit of speculation, but I'm still at Celtic," said Naylor in the Sunday Mail. "It's flattering, but nothing has happened yet.
"I'll keep training and hopefully win back my place. I'll be totally professional. That's the way I am.
"I've been linked with Portsmouth and it's nice to know some managers believe you could be useful to them.
"But I don't know what will happen. The last day of the transfer window will be hectic. If I stay with Celtic, that's fine.
"I've been impressed with Tony since he came in. He's different class and a straight talker who tells you how it is."
