Didier Drogba has labelled this campaign the 'hardest' of his Blues career while Fernando Torres admitted he 'just can't score' in a Chelsea shirt.

Chelsea sit 5th in the Premier League, 17 points from top spot, and have been largely disappointing under new boss Andre Villas-Boas, despite remaining in both the FA Cup and Champions League.
Chelsea's 1-1 draw with Birmingham on Saturday means they face a replay at St Andrew's and their next fixture sees them up against Napoli in the Champions League.
"It is the hardest season I've known here," said Drogba. "The players and fans are used to being in the first two or three, but this is different."
"You know how it is when you come with a lot of ambition and it doesn't go the way you want, it's difficult." Meanwhile, misfiring stiker Torres admitted he needs to pick up his performances. "Personally I have to improve. In my time at Liverpool there were games where I would not be playing well or I would be doing nothing but every time I touched the ball I scored. It's such a strange feeling now because I am feeling better than ever physically. But I am not finding the chances and, when I do find the chances, I cannot score," he told ESPN.
The 27-year-old has scored just three goals in 34 league appearances since his �50m switch to Chelsea over a year ago.
