The former Motherwell man was the one player generally exempted from criticism in the season just ended with his performances providing a beacon of hope.
Scott Brown has already left to join Aberdeen, with doubts over whether Ryan Christie, Olivier Ntcham and Tom Rogic will be around next season retaining Turnbull looks essential for the expected rebuild.
The other aspect causing concern is the reported £7m transfer fee. Two summers ago Celtic picked up £25m from Arsenal for Kieran Tierney with the London club likely to be able to double that fee if they were to sell the defender.
Turnbull hasn’t got close to the levels Tierney hit at Celtic but equally he’s worth a lot more than a third of the fee picked up from Arsenal. In January Celtic received a fee of £11m from Bayer Leverkusen for Jeremie Frimpong.
With a contract running until June 2024 Celtic appear in control of the situation but with no manager and Season Ticket renewals still to be announced the club are currently in a vulnerable position.
How should Celtic react to a £7m bid for David Turnbull from Aston Villa?
Delete! Throw in McGinn and we'll discuss
Accept, decent dough, build the war-chest
£7m for David Turnbull is the best joke I’ve heard in a while. Honestly Celtic should not even think of selling him for anything less than KT money based on his age, potential and what he’s already done in a short time. I expect the team to be built around him next season.

There’ll be a list of players the length of my forearm leaving the club this summer.
David Turnbull won’t be one of them.

Absolute non starter. We should be building the team around him

Never happening. Especially for 7 million, would need to be at least double to talk about it
