Rio Ave vs Boavista Prediction Tip Reason: "Just 2pts separate these two sides as we approach the halfway mark in the league. Rio Ave, in 7th place, have only won 3 of their 8 home games this season, and are on a 2 match losing streak in front of their own fans. The away side actually boast the 2nd best away defence in the league with just 5 goals conceded in 7, though they also don't score all too many. They've also had more rest than the hosts, who played in the cup in midweek."
