Dec 15 (Reuters) - Chelsea manager Enzo Maresca said his weekend comment about spending the "worst 48 hours" since joining the club needed no further explanation as his team focus on Tuesday's tricky trip to Cardiff City for a League Cup quarter-final clash.

After Saturday's 2-0 Premier League home win over Everton, Maresca said his players had been through a "complicated week," adding that "many people didn't support" them.
