The pair have scored 11 goals between them so far this season and Drogba notched his 100th for the club in the defeat at Wigan.
"Well done to Didier on reaching 100 Chelsea goals as when you think how much time he spends up front alone, how demanding the modern game is on the central striker, you realise what a special achievement it is," said Terry.
"This season he's playing as well as ever and it is easy to believe the next goal is never far away.
"It is the same with Nico, who is scoring regularly again and that winner in Cyprus really was a fantastic strike."
One of the major reasons for their success is the supply of through balls from midfielders like Deco and Frank Lampard.
Manager Carlo Ancelotti's systems have no use for wingers, so the supply to the strikers comes through the centre and so far this season, apart from the defeat at Wigan, it has worked perfectly.
"You need to mix guile and quality in order to try and penetrate defences through midfield because sometimes without the use of wingers, you need that clever pass through the middle to try and put people through," said Lampard.
"When you have the likes of Didier and Nicolas up front you have to find them and use them and their qualities - that's their pace, their power, their strength and their finishing abilities.
"There's no point playing through midfield all day and keeping the ball. It may look quite pretty but the main idea is to get them in front of goal and I think we've done that so far."
