The game Juventus will be playing against Inter and Lazio won't be easy for Juventus, this two teams are ahead of Juventus in points and I will say they have been better than Juventus in performance. I can't say if Juventus will have that strength to challenge Lazio and Inter.
I don't think you have been following Juventus games. If not for the point deduction Juventus would have been in the second position. Lazio happens to be a fortunate club they were able to climb when Juventus dropped due to point deduction. In the games Juventus have played this season against Inter and Lazio the haven't drawn any Juventus won all. The last game where Juventus and Inter ended in a red cards from both side, Juventus still won. Juventus will win their next three games for sure and that will push them closer to the top 4
