Former Manchester United captain Roy Keane has questioned Arsenal's top four chances this season.
Keane has lumped the Gunners in with his former club when discussing the competitiveness of the top four race this term.
The Gunners are regarded as Manchester City's biggest title threat.
But Keane told the Stick to Football podcast: "We always talk about trying to close the gap to Man City, but I think the challenge for some of these teams including [Manchester] United is what's going on around them.
"Liverpool are improving, Newcastle, Villa...that's the challenge I think Arsenal and United have to worry about."
