It is understood that a fee of around £50 million could be enough to secure the transfer, and former Gunner Perry Groves is of the opinion that the England international is well worth that amount.
Speaking on talkSPORT, he said: “He’s English. He’s young – he’s 23. He’s proven that he can play in the Premier League.
"He’s good on the ball, he’s good at bringing it out from the back. He’s very calm.
"He can play right-back, he can play as a holding midfield player, but as a centre-half, I think he has the ability to be better than John Stones and Harry Maguire from what I’ve seen of him.
"As an Arsenal fan, for £50 million, happy days. It’s a statement of intent.”
