Unai Emery is under huge pressure at Arsenal , with the club’s recent 2-1 loss to Eintracht Frankfurt in the Europa League meaning the Gunners are now without a win in their last seven matches in all competitions.
This is Arsenal’s longest winless run since 1992, when George Graham oversaw eight games without a victory.
Speaking to talkSPORT, the midfielder said: “I don’t think he will be there on Sunday. They really have to make that big decision.
“Edu and those who are making that big decision have got to ask ‘Has he lost the dressing room?’
“I’m not there on a daily basis but they are. They see what is going on around the dressing room.
“If he has lost the dressing room then you have got to make a decision today.”
When asked who he thinks should replace Emery, Parlour gave his backing to former midfield partner Patrick Vieira.
“I have always said Patrick Vieira,” he answered. “I would take a chance with him.
“These sort of lucky breaks sometimes – I know for a fact he would be like Frank Lampard [at Chelsea] and the fans would give him a chance.”
However, with Vieira currently in charge of Ligue 1 side Nice, it is more likely Emery’s assistant Freddie Ljungberg will be placed in temporary charge.
“Freddie Ljungberg I would have to go with at the moment,” Parlour added.
“I am sure behind the scenes they will be really sounding a few people out.
“I know the Wolves manager has been mentioned, [Mauricio] Pochettino with his payout, I’m not sure how that will work.
“I am not too sure about Eddie [Howe] at the moment but he has done a wonderful job at Bournemouth. He might not want to go. He might be happy to stay at Bournemouth.”
