Jamie Carragher believes Arsenal's club-record capture of Mesut Ozil is looking like a waste of money, and feels that the Premier League title challengers would have been better off signing Liverpool playmaker Philippe Coutinho.
In his latest column for the Daily Mail, the former defender turned football pundit lavished praise on the diminutive Brazilian, and also had some harsh words for the £42.5million man, in the aftermath of the Reds' 5-1 demolition of the Gunners at Anfield on Saturday.
"Arsene Wenger blasted his whole team after Arsenal's abysmal showing at Anfield but the one person who epitomised their lack of commitment was Mesut Ozil," he said.
"Lazy without the ball and weak when on it, the German appeared to be a shadow of the player who gained so much praise when he moved to England in the summer.
"Comparisons with Liverpool's own playmaker, Philippe Coutinho, only show up Ozil's deficiencies more."
Saturday's disappointing defeat meant Arsenal were overtaken at the top of the Premier League table by Chelsea, who strolled to a 3-0 victory over Newcastle at Stamford Bridge.
And, with the Gunners set to face champions Manchester United at Emirates Stadium on Wednesday night, they can't afford another slip-up in what looks like being a season-defining month for the club.
Liverpool, meanwhile, are sitting pretty in fourth spot, and Brendan Rodgers' side have a realistic chance of qualifying for the Champions League next season - something they must achieve in order to keep hold of star players like Coutinho and Luis Suarez.
