Celtic boss Neil Lennon says the club have not received an improved offer from Arsenal for Kieran Tierney.

The Bhoys want at least £25m for the Scotland international after rejecting an initial bid of £15m from the Gunners.

Lennon said: "I have taken no notice of the headlines. I am well aware of where we are in terms of the situation.

"I spoke to Kieran in Austria and to be honest I haven't really seen much of him because he came back early for rehab, so has not been on the training ground as yet.

"It can be an unsettling period for any player and that is understandable but until a club comes up with any sort of realistic valuation of the player we don't have to do anything and we won't.

"It's as you were. Kieran is getting on with his rehabilitation and we are getting on with what we have to do here."

Napoli are also monitoring the situation at Parkhead.
