We were rubbish in 2011 and had no business making the final, and in 2009 we played a significantly weaker team than the one in the 2008 final. They were a very good side, but this Madrid team would match them very close. You have to remember that domestically where Barca won 3 La Ligas, that Madrid team were nowhere near this one. Since then they've added Modric, Kroos, Casemiro, Bale, Carvajal - essentially a whole top midfield and several crucial players. Their midfield in 2011 against Barca in the semi was Lassana Diarra, Xabi Alonso and Arbeloa..
That Barca midfield was obviously very strong combined with a peak Messi, but this Madrid side are on a whole new level to the one that Barca faced. If Real win 3 CL's in a row then they're easily up there with that Barca team in terms of success. Their only real blip is one La Liga during that time - but the Atletico Madrid team of the last 4 years are a lot better than the one that Barca team faced (as shown by a La Liga win and two CL final appearances), and the Barca team of the last 4 years with Messi, Neymar and Suarez are a lot better than the Madrid team that Barca faced circa 09-11.
