Arsenal have enjoyed their best-ever start to a Premier League season having won nine of their opening 10 games and boasting a four-point advantage at the top of the table.
Despite this, Manchester United legend Rio Ferdinand's "worry" for the Gunners could still come to fruition as they look to continue their stellar start to the campaign with a win away at Southampton on Sunday. The former Old Trafford star was speaking earlier this season when he confessed he feels Arsenal's central midfield could be a problem area.
Granit Xhaka and Thomas Partey have been near faultless so far this term, but Ferdinand's comments still ring true weeks later. "I just worry about your [Arsenal's] central midfield," he told his Vibe with Five YouTube channel.
