I'm extremely not worried about Braga's performance. In the past seasons, Braga haven't been playing their best in the league. it was recorded that the won only 19 matches out of 34 matches that was played last season, that made them settle in the fourth position in the league table.
Braga did qualify for the European competitions and this is an indication that they will perform at their best. Let's hope they can keep the momentum at the same pace! As for their local league, I'm certain they're not among the title contenders cause for the past few seasons, they have only achieved a top four position. Braga are always behind Benfica, Sporting Lisbon and Porto in the league. it seems like they are comfortable in that spot.
