Mancini admits juggling the demands of the Champions League and the Premier League is a concern for him
"Playing Premier League needs a lot of strength and energy. It is very hard playing again after a Champions League game," said Mancini.
"Even the teams who have played Champions League for many years sometimes have problems, but we want to try to do well in both competitions and get to the second stage."
