You can only beat what's in front of you so credit to Inter for taking maximum points even though Milan and Sampdoria are most likely to sack their coaches soon, it's not Inter's fault though.
Now they have to play two elite teams, this is how you know if they're genuine contenders. Even if they lose against Barcelona and Juve, it's the way that they play that's important. Barca will have 70% possession but with that a 1-0 loss won't look bad. How they respond in the next game is telling, at home will they press or will they be defensive? A smash and grab performance like our loss to Man Utd?
