Today all the fans will be concentrated on cheering the old lady in the Mole derby. It will be a tough and difficult match which however matters a lot both for the city and for the league table. I think that with a bit of commitment Juventus can really easily catch up with AC Milan if not overtake him so now top of the rankings and watch out for the grand final 
If what you mean is Juventus, that means Juventus must win more in the remaining matches, especially in today's away match. Because the gap is six points with AC Milan, which is in second place, it is not easy for Juventus to catch up again from now on if AC Milan itself is still competitive enough in winning matches. But if you mean the Coppa Italia match, I think we still have to wait another two weeks to see how the Juventus team performs before the match starts.
