There will be fireworks when Porto and Benfica face each other in “O Classico” on Sunday evening. The Dragons made a perfect start to the season and they will be aiming to keep their 100% record intact this weekend. Defender Nehuen Perez remains in the recovery room, but the 25-year-old defender should be the only absentee in the home team. A man to keep an eye on in the home team will be Samu, who has been scoring goals for fun in the early stages of the season. The Eagles, on the other hand, aim to make amends for the Champions League loss to Chelsea. As Jose Mourinho is likely to adopt a defence-minded approach in the Primeira Liga derby, we believe that there is a big value in betting on under 2.5 goals. With Antonio Silva limping off with injury in the midweek defeat, fellow defender Tomas Araujo is widely expected to start against Porto.
