That’s according to journalist Duncan Castles, who thinks Tierney would prove much better value than £55m Manchester United target Aaron Wan-Bissaka.
Tierney, 22, has made 170 appearances for Celtic since coming through their academy in 2015.
And it seems his consistent displays for the Scottish champions have caught the eye of Arsenal, who are in desperate need of defensive reinforcements after another miserable campaign that saw them miss out on Champions League qualification once more.
Castles claims Celtic are demanding £30m for Tierney, £25m less than the reported price Crystal Palace are demanding United pay for Wan-Bissaka, and he believes the Gunners are getting the better deal when drawing comparisons.
“If [Arsenal] were to end up paying £30m for Kieran Tierney, that would represent a bargain compared to the £55m that Manchester United have agreed to pay for Wan-Bissaka”
He said on The Transfer Window podcast: “If [Arsenal] were to end up paying £30m for Kieran Tierney, Celtic’s asking price, that would represent a bargain compared to the £55m that Manchester United have agreed to pay for Wan-Bissaka, for example, who has far less experience, certainly hasn’t played Champions League football, has only played as a right-back in senior professional football, so you don’t have that adaptability.
“But of course, prices are determined by the club you’re taking him from, and in this case Arsenal will be well aware that Celtic have been open to selling Tierney for some time.
“Last summer, Everton were pretty aggressive about trying to sign Tierney.
“It was made clear to them that Celtic would do a deal, similar situation, Celtic were prepared to cash in at the right amount of money.”
Another defender being tipped to join Arsenal this summer is United centre-back Eric Bailly.
The Ivorian has only made 18 appearances in each of the last two campaigns at Old Trafford, plunging his future at the club into doubt.
Despite reported interest from the Gunners, though, Castles insists Red Devils boss Ole Gunnar Solskjaer doesn’t plan on selling Bailly.
“I know that [Arsenal] have a longstanding interest in Eric Bailly and have approached him to find out if he’d be interested in moving to Arsenal,” he said.
“But the question mark in that deal has been: would they have the money to give Manchester United back what they paid to sign him three seasons ago?
“That essentially came down to whether they qualified for the Champions League or not.
“And when they didn’t, it doesn’t look like they’re gonna have the resources to get Bailly out.
“And Bailly himself has been told that Solskjaer doesn’t want to sell him.”
