The Gunners moved back up into fourth place with a win over Manchester United and are just one point behind third-placed Tottenham, while they overturned a 3-1 deficit to progress to the quarter-final of the Europa League.
Arsenal were handed a tough draw against Napoli but Pires is backing his old club to go all the way as well as holding off United and Chelsea in the fight for a top-four place.
I think Unai Emery is a good manager, hes won some titles with Sevilla, with Paris Saint-Germain, the Frenchman told ESPN.
For the end of the season, he has two targets: to reach the top four and – why not – to win the Europa League competition.
Thats why Arsenal are in a very good way and thats why Im very confident and very positive always when I talk about Arsenal.
I think they can reach both targets. Of course it will be very difficult, but the squad is very good, we have good quality.
