Arsenal defeated Norwich 5-0 on Boxing Day to see them consolidate their fourth-placed position in the league table.
But Perry Groves believes that the Gunners are still outsiders to finish in the top four come the end of the season.
Groves feels Ralf Rangnick’s Manchester United will be their main challenge.
“They[Arsenal] need help,” Groves told talkSPORT.
“I’ve watched them in games and when there’s a period in games that’s not going your way, when you’re under the cosh, you’ve got to be able to get through that period.
“It’s a ten, 15 minute period where you knuckle down when you don’t concede.
“Watching Arsenal play when we do go through that period in games, it looks like we’re going to concede.
“I can’t seem him doing much business in January because he knows this is his team now.
“Let’s be honest if Ralf Rangnick is half the manager that everybody says he is at Manchester United, if he doesn’t get them fourth with their quality then he should be nowhere near there at the end of the season.”
Going into their Premier League clash against Newcastle United on Monday night, Manchester United sit seventh in the table.
