Andriy Shevchenko hopes to see action for Chelsea this week against Champions League opponents Olympiacos.
"I felt very fit and then I suffered an injury," said Shevchenko, who had not played since scoring twice in a 4-4 draw with Aston Villa on 26 December.
"My game was getting much better and then again, another injury. I understand this is life, but it's important to be involved in the team. I try to help the team, and give my contribution."
