Sorry to mingle through a thread which is none of my business, but this is a topic I'm particularly interested (I always like to follow UEFA coefficients closely and appreciate the system a lot). Just want to add some outside perspective on all this.
First, anyone can agree that Manchester City have been unlucky on their draws in both last editions. I don't think this is a reason to be pessimistic, unless you're a firm believer in fate.
Second, I disagree with the much brandied point of the system being designed to perpetuate the status quo. In a way, it contributes to that, but it's a minor contribution, and I think the main goal is to prize consistency and European dedication. Naturally UEFA will want to reward the teams that take their competitions more seriously, it's the only explanation for winning the EL giving almost the same number of points as winning the CL. This is actually the only thing UEFA actually makes to value the competition, because we all know that financially it isn't worth it, and with games at Thursdays it's a major disadvantage for teams battling in more than one front.
Plenty of teams have been on pot 1, came down through the rankings, and later returned. A team like Porto, from an economically very poor country with a comparatively dire league got there. The likes of Benfica are very close to pot 1 as well.
Manchester City will be able to get there without major hassle. Arsenal will get out of there sooner than later. It takes time, it's not an instant reflection of the power of the teams, it's a prize for dedication and pedigree, which takes time to build. You just have to perform better in Europe. Playing in the Premiership is different from European football. Experience is extremely important, not only individual experience (of which you have plenty), but team experience as well.
Everyone is making a bit too much of this. You won't be unlucky with the draw every season, and even if you are, you will eventually be able to cope with that obstacle. Like someone said before, if you took 1 point out of two games with Ajax, you're putting the cart behind the wheel by worrying too much about UEFA coefficients.
Good luck out there.
