Campbell says current Arsenal squad capable of greatness
The 35 year-old defender maintains there is every reason to believe this current squad - set to finish third - can develop into world beaters.
"The main thing is you have got to get the right balance," Campbell said. "There is a fantastic amount of talent here and we just have to believe we can win a major trophy - and you also need a bit of the rub of the green now and again.
"That said, I believe you make your own luck in the game - how you play, how you conduct yourselves, how you approach matches, making sure you are seriously thinking about football, you create luck with all those things combined.
"Training-wise, you have to work on your weaknesses, preparing yourself properly for the game, on and off the field. It is not that you have to be locked up 24/7, but I think all these things do add up - you ensure that things go your way by doing all the things which come before you actually step on the pitch."
Campbell maintained: "We have got a lot of that in place here and I am sure that, once everything comes together, there will be no stopping Arsenal winning trophies season after season.
"You have to truly believe in your skill and trust that you can do something. Wherever we finish, we will have to build on it and keep on going."
