Galatasaray suffered a blow to their title challenge on the weekend following a 2-2 draw against Istanbul minnows Başakşehir.
The draw saw Beşiktaş move two points clear of Galatasaray at the top of the table.
The Lions were in need of moral and it came in the form of former striker Didier Drogba.
Operation Lions saw Drogba sporting a military camouflage outfit and beret infiltrate the Galatasaray training grounds in Florya and make a surprise appearance.
The Galatasaray players appeared glad to see their former teammate who gave words of encouragement and lifted the mood of the camp.
Drogba joined Galatasaray on a free transfer from Chinese club Shanghai Shenhua in January 2012.
The Ivory Coast international spent two seasons at Galatasaray and scored 20 goals in 53 games.
The 37-year-old won the Süper Lig, Turkish Cup and reached the quarter-final of the Champions League while at the Lions.
Drogba returned to Stamford Bridge last summer and has scored six goals for the Blues this season.
