Arsenal's Invincibles points tally wouldnt have won the league half of the seasons over the past decade. I think it's going to be another close title race this season and it's unlikely any team would be far enough ahead by Feb/March to the point where their main focus became remaining unbeaten and actively playing out cagey draws.
In our case, I don't think even having a chance of going unbeaten would see us change the way we set out and play games. We usually play to win, even if it means we might fall foul to smash and grab style defeat. As an achievement, the centurions season was much more representative of who we are under Pep.
None of the above is to say that it wasn't a huge achievement for Arsenal to go unbeaten and I doubt it will be repeated again.
