Abraham grabbed his first Champions League goal in the encounter, taking his season tally to eight goals in 10 matches this season.
Ferdinand marked Drogba during his prime at Stamford Bridge, and the former Manchester United defender saw shades of the Ivorian in Abraham's game.
“I saw elements in Tammy's game that I haven't seen as much as I would have liked to before," the ex-England defender said.
"His hold-up play, coming to the ball, bringing others into play. There were some balls that came into him that were Didier Drogba-esque.
"I think he's developing nicely, he's scoring goals, he's scoring different types of goals and I think he's a threat.
"This touch here (for his goal), when this ball comes to him, it's a magnificent touch because it's not the perfect ball. He adjusts his feet beautifully and the finish, the calmness to do it like that."
