I don't buy that our past failures when in this position are that relevant. Wenger is a constant, but he was there when we were winning titles too.
The difference I see now is a spine of world class players, I don't think we've had that in the last 10 years.
We've won the two FA Cups which show we can finish the job, we've won a couple of big league games this season - ones we traditionally have cocked up - and we have players like Cech (what a difference he has made already), Sanchez and Ozil who know how to do it at the business end of the season.
We'll have to wait till May to see whether that's enough and I can understand some skepticism but it is a bit wearying how so many expect us to fail and refuse to see any signs of hope.
