Drogba backed Samuel Etoâ€™o and Fernando Torres - both on target in a 3-1 aggregate win against the Turks - and said the know-how of Jose Mourinho, Petr Cech, John Terry and Frank Lampard will make the difference.
"They know how to handle this situation. They know how to win important games. When I was there, if we were top of the league at this stage of the season, we never let it go.
"So the players who were there then will be very important if Chelsea are to win it this season."
