Sporting vs Rio Ave prediction (Over/Under)

Sporting are impressive in offense recently as they have scored three goals in each of their latest two Primeira matches against Academica and Ferreira. Also they recently have scored 6 goals when visiting Setubal. Sporting are second in the league but they can reach the top of the table if they win today so they should be very motivated to show their best football. Sporting are impressive at home averaging two goals per match. Their offense is impressive with Islam Slimani, he is the second in the top scorers list with 16 goals. Sporting have scored twice in the first head-to-head match against Rio Ave on the road and they should dominate even more at home having in mind Rio Ave are weak in defence. They recently conceded 5 goals when visiting Braga. On the other hand Rio Ave are not that bad in offense too, especially when playing on the road. They have scored 16 goals in nine away games played, they have found then net in the first meeting with Sporting this season. I expect them to add a goal today also and a high scoring match is my prediction.
