Robert Pires insists Arsenal must do all they can to win the Europa League in order to qualify for the Champions League.
The former Gunners winger wants his old club to focus on the competition, and believes Manchester United's 2016-17 success is a prime incentive.
He said: "The Europa League has to be Arsenal's priority now, already.
"The objective has to be to do what Manchester United did last season- they are a good example.
"United won the Europa League and went straight into the Champions League- for Arsenal it is very important to get this state of mind.
"It's a trophy, a good trophy, so it's very important. And this season is the last opportunity Arsenal have of making the Champions League".
