McReggae,
A draw would have given Arsenal 10 pts, Shahktar 7 pts, Braga 6 pts and Partizan 0 pts
Lets Assume we lose the next game to Braga and the same time Shakhtar win against Partizan....that would mean Arsenal 10 pts, Sharktar 10 pts, Braga 9 pts and Partizan 0 pts
In the last game Arsenal face Partizan while Braga face Shahktar....Once again lets assume we lose the match, we would still be on 10 pts. A Braga win would give them 12 pts while a Shahktar win would give them 13 points. A draw would give Shahktar 11 pts and Braga 10 pts.
With a goal difference of +11 there's no way Arsenal would have been knocked out. I hope you've also noted that I've assumed we lose both of our remaining matches.
Btw Arsenal have lost one match in the CL and several in the EPL but can still match Man Utd in every competition.
