We're quite lucky we got Shaktar as the top seed as Napoli are probably the strongest team from pot 3 and Feyenoord are decent. No excuses though we should be topping that.
Spurs' draw isn't as bad as it first seems. Dortmund aren't the team the were over the last few years. It will come down to those games as apoel should be a given and they're both unlikely to trouble Madrid.
Chelsea should be fine too, Roma are a decent side but not somebody they should be worried about really. Just a fight to see who finishes top.
United had harder Europa league ties than that group, jammy bastards, they'll top that group comfortably.
Liverpool could not have got an easier draw if they hand picked their group. a decent draw would have seen them go out, again, they should top that group.
Spurs and Chelsea could be in big trouble come the next round if all the other English teams top their groups. Lets say things go as expected and Chelsea fail to top the group Chelsea will be looking at Madrid, Bayern, PSG and Barca/Juve and Spurs if they manage to push Dortmund out of second are looking at the same. Scary for them.
