Chris Sutton believes Celtic defender Kieran Tierney should command the same transfer fee as Aaron Wan-Bissaka in the summer transfer window.
Manchester United are thought to be closing in on a deal to make the England Under-21 international their second signing this summer.
Reports in England are suggesting that Manchester United have agreed a £50m transfer fee for the Crystal Palace full-back.
Arsenal, meanwhile, are thought to have failed with two bids for Tierney after Celtic rejected £15m and £18m offers.
The Scottish Premier League champions are thought to value Tierney at around £25m following his impressive development at Parkhead.
But Sutton took to Twitter to suggest that Celtic should charge Arsenal the same transfer fee, adding that the Scottish side should “dig their heels in”.
Sutton wrote on Twitter: “Not so long ago John Stones went for £50 million and Celtic sold Virgil Van Dijk for £13 million… Wan Bissaka £50 million to United…Let’s hope if Celtic do sell Kieran Tierney they get a similar fee as he is every bit as good..”
He added: “Wan Bissaka is not twice the player Tierney is. They are very similar attribute wise…Stones was never a better player than Van Dijk yet was four times more…English clubs get players from Scotland on the cheap. About time Scottish clubs dug their heels in…”
Tierney has won four Scottish Premier League titles, two Scottish Cups and two Scottish League Cups since breaking into the Celtic team as a teenager four seasons ago.
The Celtic left-back has made 12 appearances for the Scottish national team, although Liverpool FC defender Andy Robertson has moved ahead of Tierney in the pecking order.
Although Tierney is a seasoned international for Scotland, Wan-Bissaka still hasn’t made his full England debut despite racking up appearances at Under-21 level.
Arsenal haven’t made any signings in the summer transfer window.
