Portuguese side Braga have upset Celtic and Sevilla to make it to the Group Stage of the Champions League.
So what problems can Braga cause Arsène Wenger and his side tonight? We asked Portuguese journalist Luis Baila of RTP for a Braga perspective of the game.

IMPRESSIONS OF ARSENAL
Many years ago a Braga coach saw Arsenal and liked what he saw. When he arrived at Braga he said they needed red shirts like Arsenal. The shirts are similar because London and Arsenal are an inspiration to Braga, the city and the club.

THE EMIRATES EFFECT
They are confident because they are coming off the back of a good performance against Porto. They have confidence but they have respect for Arsenal because they are one of the most important clubs in Europe. They are at home in a big stadium so they have the respect of Braga.

TALKING TACTICS
Braga plays very well with the counter-attack and can make a surprise at the Emirates with this counter attack. That is how I expect them to play on Wednesday night. I don't think they will go all-out attack.

REASONS TO BE CHEERFUL
They played Porto at the weekend and they are the two title contenders. It was a great game that finished 3-2 to Porto but Braga played very well. Either side could have won. It’s very difficult for Braga to win at the Emirates but it is possible because Arsenal have a number of injuries so Braga have a chance.

CUP FEVER
Braga is a club with history in Portugal but not with history in the Champions League. Last year they finished second in the championship and they have already eliminated Sevilla in this season's Champions League. Seviila have a budget ten times that of Braga. Of course they aren’t a candidate to win it but they can do well and maybe surprise a few.

THE ONE TO WATCH
The key player in their attack are Lima - he scored lots of goals in the qualifying rounds. In midfield the most influential player is Aguiar. He made a goal against Porto at the weekend.
