Edinburgh meanwhile finished bottom of their Pool, with six defeats from six, and now the focus returns to the RaboDirect PRO12 - where the Gunners currently sit in ninth place.
The Scottish side have now lost their last seven league and cup outings, but aren't in RaboDirect PRO12 action until they face Munster on 9 February.
And although unwilling to make excuses for his side's defeat against Mark McCall's side, Bradley acknowledged he did not know what lay in store for him at the Murrayfield outfit.
"It would have been hard to deny Saracens," former Irish international scrum half Bradley told The Scotsman.
"They were by far and away the better side, they deserved their win and they deserved to get the bonus point as well. They deserved their luck on the day.
"Obviously this was a very disappointing campaign for us. I am in my second year of a two-year contract, so it is up to the people whether they want to extend my contract or not."
