Either way Bologna will have a place for UEFA Champions League next season, whether they finished fourth or fifth. I find Atalanta quite in form this period especially after picking UEFA Europa League from Bayer Leverkusen by three goals.
Anyway, top positions are almost fixed but relegation zones teams represented by Empoli up to Cagliari are still in doubt about which team to relegate from it.
Both Bologna, Juventus and Atalanta are already got their tickets to Champions League. Their ending positions in Serie will only affect their money rewards from FIGC a little bit. A bigger thing to view is will Atalanta complete this season at a fourth of third position. This is important for Serie A and AS Roma because if Atalanta get good points from their 2 remaining matches, and complete this season at a position higher than the fifth, Serie A will not get a sixth ticket to Champions League and Roma will have to play in Europa League.
If Atalanta win both matches, they will surpass Juventus and take the third position. If they win only one match, they will take a fourth position from Bologna and how many points will they get in last two matches is interesting to see.
