Former Arsenal manager George Graham has claimed that the team needs a new spine if they are to challenge for the Premier League title.
The Gunners are currently fifth in the table, 13 points behind leaders Chelsea.
Graham says that Arsene Wenger must invest heavily in the market during January to make his side competitive.
"All Arsenal fans would like to see new players right down the middle," he told talkSPORT. "They need a new goalkeeper, a centre-half and a defensive midfielder.
"With all the talent they've got in midfield, they're up there with the top teams in the league, playing attractive football when they're in possession.
"When they don't have the ball, though, there are too many players who don't want to win it back early enough."
Wenger has stated that he is looking to sign a defensive player this month.
