they depend on the uefa team ranking found here (
UEFA Team Ranking 2010 )
the problem is that they give same points for a team winning a uefa cup game and team winning cl game..
and bonus points they give isnt much for cl teams over uefa cup teams.
hence why sevilla ( twice uefa cup winners in last 5 years) are that high..
also teams like bremen, hamburg, zenit who done nthg in CL are high as well because of uefa cup.
Italian teams are forced to do very well this year (
UEFA Country Ranking 2010 ) because they just have three points more then german teams. If germany collects more points again then italy this year, then in 2011/2012 italy will start to participate with 3 teams.
