The former Portuguese international winger points to Manchester United as proof that a managerial change can hurt the club, backing Wenger to remain in charge beyond the summer.
“I believe in the boss. For sure he is going to be there next season,” Boa Morte said.
“Arsene Wenger created the philosophy we have at Arsenal. People can talk and protest but I don't remember any other manager being an Invincible.”
“Be careful what you wish for. Look at Manchester United after Ferguson left, who has been successful? Nobody. It is the same thing. We can see United's results and where they are in the table.”
Wenger has come in for criticism from the club’s supporters following a poor run of results since the turn of the New Year, surrendering top spot to surprise package Leicester City.
In a season where Chelsea, Liverpool, Manchester United and Manchester City have all faltered, Arsenal haven’t been able to take advantage and sit some 11 points behind the league leaders.
Add an FA Cup exit to Watford and a Champions League exit in the first knockout stage for the sixth successive season, it’s understandable why fans are becoming increasingly tired with Wenger.
That said, there is no guarantee that a change in manager will result in success as United have illustrated this season under the guidance of Dutch coach Louis van Gaal.
