this is what worries Inter fans because they know that Juventus has a much better stamina and physical advantage because they dont have any other matches scheduled and it is difficult to predict whether Inter will continue to stay at the top of the standings while Juventus continues to catch up on points.
It doesn't worry me, maybe because I'm not an Inter fan but I'm certain that if you ask Inter fans which they would chose between not playing in the champions league and having a lot of time to rest while Juventus plays in the champions and the league or they (Inter) plays in both competitions, I'm sure they'll chose to pkwy in both competitions.
These are the things that determine a big club. A big club plays in 3 competitions all season long while smaller clubs only plays in one, making the challenge and pressure bigger for the bigger club.
Inter don't seem like a club that would let Juventus use that as an advantage over them. The serie A title race would be between these two giants; Juventus and Inter. I'm placing my bet on Inter though because they seem like a more serious team. They play better and are more compact than Juve. Hopefully both teams keeps up this momentum till the end of the season so either team don't run away with the league like Napoli did last time.
