Enzo Maresca said Friday he does not believe his Chelsea team have a "discipline problem" following a spate of red cards as he prepares for the visit of Premier League leaders Liverpool. Forward Joao Pedro suffered the same fate late in Tuesday's Champions League match against Jose Mourinho's Benfica but Chelsea won 1-0. "When it's a red card for bad intention or for bad discipline, it's different compared to the Manchester United red card or Brighton red card," he said. Again, I don't see any discipline problem, even if we consider three or four red cards, that is not something normal. "Most of the games where we didn't get the points is because they were games very complicated for us in terms of, again, unfortunately, red cards," he said.
