That true of what was mentioned by hd49728, the reason why they are saying it, because they think a penalty given by the referee is a controversial penalty that makes juventus win. However, Juventus has good quality players, we can't avoid it. forget about the issue, now Milan will be against Juventus. in 5 matches Milan have never won. They also get red cards in 3 matches, i think thisa matches will hard to Milan to stopping their bad record. Also lot of people want Milan to win and keep the chances of Lazio becoming a scudetto.
Milan have bad records in recent matches against Juventus and from their general player quality, I don't think they will manage to get a draw or a win in the coming match.
Chances for Lazio, I don't see such. Before latest bad matches from Lazio and Inter Milan, I did not believe they will have any opportunities to win the scudetto this season. We already talk about the better quality in squads of teams but expanding it further to substitution benches, Juventus even have much stronger quality and strength for their substitutions. It makes different in the long race for the Scudetto.
