In my opinion Braga is clear favorite of today's match up and have all required tools to make comfortable win with at least 2 goals difference.

Braga coming for this game in great form as they won 4 of last 5 matches (in each win scored more than one goal). They failed to win only against strong Porto (0:0). Braga plays excellent season, they are in top3 in league table with realistic chances for Champions League spot. In addition to that they have great chances to win Cup so I'm sure they will want to finish this tie already today.

I see huge difference between both teams in terms of quality, ambitions and potential. Nacional plays in second league, but even there they are not good enough as they are just above relegation zone. In addition to that their form is simply horrible. They lost last 3 matches in a row, all of them with at least 2 goals difference (0 goals scored, 9 goals conceded). Confidence in team for sure is on very low level.

On those circumstances I can't imagine any other result than comfortable win for guests.

在我看来，布拉加在今天的比赛中是最受欢迎的，他们拥有所有必要的工具，以至少2个进球的差距轻松取胜。

布拉加在这场比赛中表现出色，他们在过去的5场比赛中赢了4场(每场比赛都进了一个以上的球)。他们只在与强大的波尔图(0:0)的比赛中失利。布拉加本赛季表现出色，他们目前在积分榜上排名前三，很有可能获得欧冠席位。除此之外，他们有很大的机会赢得杯赛，所以我相信他们今天就想结束这场比赛。

我看到了两支球队在实力、野心和潜力方面的巨大差异。国民队在乙级联赛踢球，但即使在乙级联赛，他们也不够好，因为他们只是在降级区之上。除此之外，他们的形式简直可怕。他们在最近的3场比赛中连败，而且都至少有2个净胜球(进0球，丢9球)。对团队的信心肯定很低。

在这种情况下，我无法想象除了让客队舒服地获胜之外还有什么其他结果。
