Should Brighton beat Southampton on Monday night, Arsenal will slip to 16th ahead of a visit from relegation-threatened Burnley on Sunday.
A Burnley win could lift them out of the bottom three and move them within four points of the Gunners, who are hovering dangerously close to the relegation zone.
Deeney feels the wrong result against Arteta will leave him ‘massively under pressure’ and predicts he could even lose his job.
‘But I’ll happily say I was massively wrong.
‘Arsenal are in trouble. I’m happy for them that they are at home, but if they were playing Burnley away this week I’d be very nervous for them.
‘I think he [Arteta] has to come under criticism, ultimately because of where they are.
‘For me, and I’ll go out on a limb here, if they lose [to Burnley] he is massively under pressure.
Former Spurs striker Darren Bent, however, is confident they will turn it around and insists they are ‘too good to go down’.
‘Arsenal have got good players and I like Arteta, and I think they have got the players to get them out,’ added Bent.
‘All it takes is Aubameyang to hit a bit of form, Lacazette to start scoring some goals… a little bit of something.
‘They are too good to go down.’
