Istanbul: Chelsea renew acquaintances with former hero Didier Drogba and an old rival in Roberto Mancini when they go to Istanbul to take on Galatasaray for the first leg of their Champions League last-16 tie on Wednesday.

Drogba was the hero of Chelsea's 2012 final victory against Bayern Munich, scoring a late equaliser to force extra-time and then netting the decisive penalty in the shoot-out that followed.
