With a defeat under Lazio, a dream to join top four for Juventus is mostly over. They don't need to catch Lazio on the table but they must avoid to have bigger gap with other clubs like AS Roma, AC Milan and now the gaps are bigger. With 9 matches left and 8 points less than AC Milan (4th position), 9 points less than AS Roma (3rd position), and those clubs have same total matches, Juventus must be more realistic with their target. A position to join Europa League next season is a best they can do in Serie A.
Of course they still have Europa League to fight and if they win it, they will be qualified for Champions League.
