Andy Dunn was adamant that Arsenal will not win the Premier League this season with their current squad as the Sunday Supplement guests debated the Gunners' title credentials after their win over Liverpool.
Arsene Wenger's team are now five points clear at the top of the Premier League after Saturday's 2-0 victory over third-placed Liverpool and are now being touted as potential title contenders.
However, The Mirror's Dunn believes the lack of depth within their squad, especially up front, could scupper their title hopes. He pointed to the team fielded by Wenger in their Capital One Cup defeat to Chelsea last week as evidence of a lack of quality beyond their first-choice line-up.
"This Arsenal squad, I don't think, can win the Premier League, not in its current form," he told Sunday Supplement.
"I don't think that it is strong enough; I don't think it is deep enough. If you look at the bench yesterday then there were a couple of players there that only Arsenal fans would recognise in terms of names.
"You only have to look at the Capital One Cup game, to me, to see that they are not going to win the Premier League. They have not got the options up front and I think that will cost them."
However, The Telegraph's Henry Winter, who hailed the impact of Mesut Ozil on the club and the form of Aaron Ramsey, strongly disagreed with Dunn. He insisted that the qualify and confidence at the club, along with the obvious travails of all their title rivals, mean they could win their first Premier League title since 2004 .
In riposte to Dunn, he asked: "In terms of your argument that they can't win the title, how can you say that now? How can you say that with the way they are playing and the confidence in that place, and the fact that it [the title] is so open?
"Okay we will expect the big guns from Manchester to start coming into range again and they will fly up the table and I take your point about the squad, but Arsenal in the past have won a title with 13 players.
"Okay it is a different modern Premier League era now but... there is nothing to stop this Arsenal team as it stands and with the confidence and the talent they have got in their first XI from winning the title."
To which Dunn responded: "Okay, I will slightly rephrase it. I'm not saying they can't, I am saying they won't."
Winter had earlier begun his case by highlighting the openness of the title race and by suggesting that Arsenal's current lead at the top now makes them favourites.
"This is the most open title race for years," he said. "Manchester United are coming back strong again; Manchester City you saw yesterday; Chelsea had a blip and everybody will probably say they are in crisis now but they have actually had a really good three or four weeks and have an outstanding manager as well.
"Liverpool have been outstanding with Sturridge and Suarez. So anyone can win this title. You can make a legitimate case why anyone of five or six teams could win it. Arsenal are five points clear and really should be favourites now."
