Former Tottenham striker Darren Bent says Arsenal must be careful with goalkeeper Aaron Ramsdale.
Bent can see Ramsdale leaving the Gunners in January and strengthening a direct rival.
He told talkSPORT: "This is where the sticky point is because when you look at the league table, and you start thinking about Aaron Ramsdale, I think he can pretty much go not everywhere but there are a lot of clubs out there I believe he's better than their goalkeeper now. [Tottenham], I'd say Villa is a no, Martinez is a good goalkeeper.
"Newcastle, I'd have him over Pope. I think he's better than Onana, it's opinion isn't it? I think he's better than West Ham's goalkeepers."
Bent added: "We've just named four clubs like that where he's better. I don't understand why you'd want him to go and make your rivals in and around you better."
