Being able to stay unbeaten in the league is the test of any team - whether you're playing against opponents from the top, middle or bottom of the table.
Arsenal's achievement of going through the whole season unbeaten, and then to start the next season and beat Nottingham Forest's record, is truly extraordinary.
Can Vieira lead Arsenal through another unbeaten season?
I can't see another club going through a whole season unbeaten, never mind for 43 games.
Certainly not in my lifetime.
What is the limit of this team's potential? I don't know. They continue to surprise me.
Last season's achievement confirmed this Arsenal side as a great, great team.
I thought it was ridiculous that some people said they had to win the Champions League or retain the Premiership to be considered great.
But now they have beaten Forest's record, I think any remaining doubters will have to acknowledge the greatness of the team, the club and the moment.
It is such a memorable achievement and anyone who disagrees must be clouded by jealously or bias.
Even friends of mine who are passionate Tottenham fans have admitted they have to applaud and admire the manner in which Arsenal play.
With Arsene Wenger in charge, Arsenal are not just winning matches and trophies, they do it in fantastic style.
It has never been in my character before, but I am regularly out of my seat and shaking my head in disbelief and applauding when I watch them play.
Wenger has plenty to smile about
Arsene's dream is to create something special, and he has added to the history of Arsenal. He is a visionary, for whom winning is not enough. It has to be done in a certain way.
There are other sides that have won titles by playing beautiful football - but they are a rarity.
Even the Johan Cruyff-inspired Holland side of 1974 did not win the World Cup, despite being the best team in the world at that time by an absolute mile.
Can Arsenal dominate the Premiership for years?
It is hard to say. You can not account for injuries, or bad luck, or players leaving the club - as Patrick Vieira very nearly did in the summer.
But Arsene's stamina is such that he seems to be more enthusiastic now than he has ever been and he also thinks there is more to come from his players.
Already though, Arsenal's feat is truly extraordinary in this day and age, when competition is so fierce and it is so difficult to win at the top level.
For the team to have gone so long unbeaten must rank, and should always rank, as one of the greatest achievements of all time.
