Chelsea manager Jose Mourinho remains confident that left-back Ashley Cole will be fit for the start of the season.
"Ashley is in the final process of his recovery and was a very good professional in his holidays," said Mourinho. "They were reduced to just a week as he was working and trying to recover from his surgery during the whole period of his holidays. We believe he can start working with the team in the United States, perhaps in the middle of next week, and he should be ready to play the friendly matches in Europe."
