Wilkins was axed earlier in the month, and since the popular assistant left Stamford Bridge Chelsea have lost two league fixtures, against Birmingham and Sunderland.
It has been suggested Wilkins' departure was the instigating factor in the Blues' recent slump.
Chelsea managed to come back from a goal down to secure a 2-1 Champions League victory over MSK Zilina at Stamford Bridge on Tuesday, Drogba has revealed the first-half display was not good enough but the Ivory Coast international has insisted Wilkins' exit is not to blame for Chelsea's poor form.
"Of course we miss Ray but the players are the same. If we lose, it is not because Ray has gone, it is down to the players. We have to try to resolve our problems because we are not playing well," said Drogba.
Chelsea named Michael Emenalo as assistant last week, with the former Head Opposition Scout promoted from within to replace Wilkins.
