Look, Inter is playing football at a title level. They didnt get this lead by chance; they did things the right way. However, let's be honest: until the end of the game, nothing is certain. AC Milan has been on a roll lately; you have to admire that. Inter needs to get ready because this is a wake-up call. The next few games for Inter are very important. Especially the ones against Milan and Lazio. A lot more than points, its speed. Now, I think Inter has the skills to stay in the game. Better schedule, and all eyes are on Serie A. Thats a big plus. But thats why we love the game, right? The excitement and the upsets. What will happen? It might get really interesting.
I am sure that Inter Milan can end this season with a title, because the point gap between them is already very far and it seems impossible if Inter Milan loses that many points in the remaining matches in Serie A this season. But you are right, they have to remain focused on every match they play, because they have to be able to lock up the title early to make them safe and more comfortable towards the end of the season.
Inter Milan have also finished their competition in the Champions League because they were eliminated by Atletico Madrid, so in terms of schedule they have a schedule that is not at all busy compared to Ac Milan which still has a schedule in the European League. They have to be able to maximize this as best as possible, all the advantages are on their side now, it would be a shame if they had to fail when they already have everything they need to become champions. However, they must be able to lock the title before the competition ends.
