Impossible to get Dortmund. Coming out of CL will almost be guaranteed to get one of the weaker teams.
It's almost a guarantee Roma would gain more coefficient points in EL. The only way they get to QFs in CL is by drawing one of the weaker group winners which is possible but odds are they will draw a top team.
Aside from this, $#@! Roma and their revenue. We earn more by them not getting out of group, and they earn less. Win-win.
