Former Chelsea great Didier Drogba does not know how he will react when he returns to Stamford Bridge with his Galatasaray team on Tuesday for its Champions League last-16 second leg, the Ivorian striker said.

Drogba won three Premier League titles, four FA Cups, two League Cups and, most memorably, the 2012 Champions League when his penalty in the shootout clinched victory for the Londoners against Bayern Munich in the final at Allianz Arena.

He scored 157 goals in 341 appearances for Chelsea between 2004-12 and was voted the greatest player in the club's history.
