Arsenal legend Ian Wright fears Chelsea could poach Emiliano Martinez from the Emirates.
Martinez has been in spectacular form for the Gunners since replacing the injured Bernd Leno in June.
The Blues are on the hunt for a new goalkeeper with Frank Lampard losing confidence in Kepa Arrizabalaga.
Speaking on the Kelly and Wrighty Show, the Arsenal legend said: "When you go to a No.2, the first thing you do is worry because you think, 'Has he had enough games? Will he be able to deal with the pressure?'
"Obviously there's no fans there, but everybody spoke about Emi and how good he is, but I didn't realise how good he was because I didn't see enough of him.
"I saw him in some cup games but he's commanding, he makes great saves, he's good on the ground, he's got everything for a No.2.
"The thing that frightens me now with him is that when Bernd Leno does come back and he is fit, why would he want to continue as a No.2 when he's played to this level being a No.1? He will surely want to go and be a No 1 now.
Wright added: "What frightens me is you look at someone like Frank [Lampard] and you look at what Chelsea's doing, you just say to yourself, "Do you know something? Can we prise him away?"
