if you win, there is a great chance that Salernitana will survive next season. but if they lose or draw, both teams still have to fight for tickets to stay in Serie A next season in the remaining matches.
Personally, I simply cannot see Cagliari going down. It's already too much that Geno is going into Serie B and as far as I know both of this teams are one of the oldest football clubs in Italy so yea ...I would prefer that at least one of them will save the season. Salernitana , have such a great passion for football in that little city and last games proved this to us so it will be very hard and challenging for any of these teams to survive to Serie A.
