Firstly, the bottling is more because you haven't won anything when you've been close (i believe thats where it comes from). With the other clubs they have won stuff even when they've had **** seasons. When the pressure is on they have gone onto win. Whether you like that definition or not (at least thats how i interpret it), i'm pretty sure thats where it comes from.
As for the FA cup, we were the league leaders but we were not at the top of our game. You're form was far better and you'd just dealt as a psychological blow first clawing back like 6 points and then dominating us at the white hart lane which is why you were deemed favourites.
Arsenal are a bunch of bottle jobs and we have been laughing at their annual february meltdowns since 2005 and they have always been known as a weak side since. Is that just a tribal hearsay as well as they are just finishing in the position (well historically anyway past few seasons they've been well off) as they are only spending the 4th most money?
I think with the spurs thing as well, is that you've had great stability under poch and he's assembled an awesome side. Irrespective of how much money he has spent, it's plain to see under his management and the players bought that you have a better side than our current one and the arse and you're very well balanced yet you still haven't challenged or won anything (arguably the past 2 years you've had the strongest side).
Anyway enough praising you, you're just a buncha bottlers
