I'd prefer it just like this:
Group 1:
Barça vs UTD
Chelsea vs Dortmund
Group 2:
Madrid vs PSG
Bayern vs Atletico
The only teams I'd fear a draw against are PSG (Ibra is in God mode right now) and Bayern (we need a lil more time, mainly Neymar at 100%). Other than them, I'd fancy our chances against anyone else, Madrid included.
We'd have a field day with UTD's space between their lines but I wouldn't mind Dortmund or Chelsea either. Both have been stronger in the past.
Way I see it: we face Chelsea in the semis. Meanwhile, we'd lose either Ibra or CR for sure and I think out of all the teams that could pull out an upset against Bayern, Atletico are the best bet. I think Pep and co. would be surprised at how resilient that team is and if they can hold us to only 1 goal in three games, they could keep Bayern out while Villa-Costa could cause a lot of problems. Dante would struggle against a ST like Costa.
I predict Bayern-PSG from that one with hopefully an epic showdown against Bayern in the final to avenge last year.
Fascinating draw, hope we get lucky.
