Drogs back to demolish Rosenborg
Drogs missed Saturday's away win to Derby but returns in place of Andriy Shevchenko who returns to warm the bench.
Chelsea will be looking to avenge what felt like a defeat when Rosenborg came to a half-empty Stamford Bridge what seemed an age ago and came away with a 1-1 draw.
History shows that that was the last game in charge for Jose Mourinho.
It will be interesting to see if Avram Grant will be looking to entertain or simply to grind out a win.
Chelsea last played in Norway when they lost 4-2 to Viking in 2002 in the Cup Winners' Cup and beat Valerenga 3-2 a couple of years before that.
The extreme cold weather will be a factor in how the match pans out tonight, but Rosenborg have never lost to an English club in Europe at home.
