Freddie Ljungberg is not the right man to manage Arsenal on a long-term basis, said former Blackburn striker Chris Sutton.
Ex-Gunners midfielder Ljungberg, 42, is in interim charge of the club after they sacked Unai Emery last month.
“Freddie said he was 100% sure they would get into the top four but based on what? It’s fantasy,” said Sutton on BBC Radio 5 Live’s Monday Night Club.
“They need to get someone in place that they are going to get a reaction from.”
Ljungberg, who played for Arsenal between 1998 and 2007, had been Emery’s assistant after working with their under-23 side but has no previous managerial experience.
In his only game in charge so far, the Gunners twice fell behind to a Norwich City side in the bottom three before Pierre-Emerick Aubameyang twice equalised in a 2-2 draw.
That result left Arsenal eighth in the Premier League, 21 points behind leaders Liverpool and seven behind fourth-placed Chelsea.
“Did you expect them to be much different?” added Sutton, a Premier League title winner with Blackburn in 1994-95. “It has been the same for the last decade and it’s still the same problem.
“They need to change the model, the recruitment. Over the summer they brought in [winger] Nicolas Pepe [for £72m] but the issues were at the back.”
Former Aston Villa and Chelsea midfielder Andy Townsend agreed with Sutton and said: “I don’t think it’s the right time for Freddie to take over, not the right time for someone who is inexperienced at this level.
“Arsenal need someone to come in and teach them about defending.
“Calum Chambers has been around long enough to see if there’s been an improvement but there hasn’t been. I don’t think he’s good enough to be an Arsenal regular.
“Sokratis is nowhere near good enough. I don’t think he would get into any Premier League side.”
