Celtic boss Neil Lennon has called on Arsenal to up their offer for Kieran Tierney.
Lennon has stressed Celtic aren't looking to sell the 22-year-old, but admitted they will support him whatever the outcome.
Asked whether the club had received another bid for Tierney, Lennon said: "Not that I'm aware of.
"Arsenal are aware of what we value the player at. He's on a long-term contract, he's an asset and we don't want to sell him.
It's going to have to take a lot more than what they've offered the first time around to give us a decision to make.
I've had a chat with him as it can be a difficult decision and bit unsettling. I've been there myself so it's important that we support him regardless of the outcome."
