Arsenal took the lead against the run of play in the 23rd minute through Alexandre Lacazette but Liverpool responded through Sadio Mane and Andy Robertson gave the hosts the lead before half time. Diogo Jota added a third for Jurgen Klopp’s men in the second half.
Wright was particularly unimpressed by the Arsenal midfield and feels the addition of Aouar is imperative for manager Mikel Arteta.
Arsenal have been linked with the 23-year-old Frenchman but have so far fallen short of Olympique Lyon’s valuation.
"It felt like a training game for Liverpool in respect of Arsenal were saying you can try and get out but we will press you," Wright told Premier League Productions after the defeat at Anfield.
"You can see that in Liverpool’s team everyone can move forward because Arsenal were starting so deep but what was evident to me was that we didn’t have that person in midfield who was comfortable enough on the ball until Ceballos came on.
"[They need] someone who they can pass the ball to, who is comfortable to receive it with someone on his back, who can pop it off, who can turn it around the corner. From there Arsenal can play but we can’t do that at the moment.
"That’s why it’s imperative we get Aouar from Lyon. He’s someone that can get on the ball and get the forwards going. You saw the chances that Ceballos made when he came on, that’s what Arsenal need."
