Fernando Torres struggled during his time at Chelsea, which Didier Drogba explains as a difficulty in adapting to being one of a large collection of great players.

"With all due respect to Liverpool, at that club, Steven Gerrard and Fernando Torres had been the kings," Drogba wrote. "At Chelsea, there were 22 kings. So I really felt for Nando, because I knew how difficult the situation was for him."

Torres was signed by Chelsea from Liverpool in January of 2011 for £50 million.

He added: "At Liverpool, the team was geared around him as their main striker. It wasn't that others couldn't score -- they could -- but they fed him the ball, they structured the team around him with the aim that he would score. That's not how it was at Chelsea."
