Andriy Shevchenko says injuries and changes of coach were to blame for his problems at Chelsea.
He said: "It will be strange meeting Terry or Rio Ferdinand again. For me and them there is a slight advantage because we know each other's strengths and weaknesses so well.
"I know Terry better than anyone else and, hopefully, I can use that information to beat him but we'll see.
"I won things at Chelsea but I would have liked to have had more minutes and scored more goals. They signed me as a goalscorer and things did not go well for me in that department.
"What with my injuries and the decisions of the coaches, I was never able to put a run of games together, which is so important for any player. In England I had good and bad times at Chelsea but it's true that people never got to see the Shevchenko that had been so good at Milan."
