Chelsea boss Jose Mourinho is delighted for Brendan Rodgers over his success at Liverpool.
Chelsea host Liverpool at Stamford Bridge.
"The manager is one of my best friends in the game," said the Chelsea boss. "So no rivalry.
"Brendan is doing fantastically but he is training every week in a calm way, every day, maybe twice a day, which is a big, big advantage. He needs to work well but he has a big advantage in the way you build your team.
"You know how much tactical work I have done since pre-season? Not much. It is easy for a team who do that every week. 'Not to be involved in European competition gives them a big advantage."
