He also claimed that Rangers are likely to go through to the next round.
Although Braga are a good side, Gauld believes that Rangers fans will make it very difficult for Braga at Ibrox.
Speaking to Bola Branca, Gauld said: “They drew at the Dragao and won at home. They defend very well and have a lot of quality. It’s very difficult for any team to go to Ibrox and I think Rangers will go through. The stadium will be full with around 50,000 fans and it will be very difficult for Braga.
