Chelsea boss Frank Lampard says they're lacking aggression after defeat at home to Brighton.
Lampard was unhappy with a lack of "contact" by his players.
Asked if Chelsea have lost their fear factor, he explained, "It might be the case but the fact is, it feels useless to hark back to the team I played in but I understand your point. Many top football clubs and we are, the last 20 years we were successful as anyone pretty much, have moments where the fear factor drops with performance.
"The top of my head, Liverpool a few years ago and they pulled it back and came again. Those moments where teams get a run of confidence against you, the only wait to fight that is to look within yourself to become a team that is not nice to play against.
"That brings me to the physical capacity of the team and the contact level of the team. I would like to see more contact, not in a bad way, more contact today. When you're short, it's hard to make contact and that can flit through the team. Whether teams are less fearful, if they are, that should be a carrot for us to turn it around to the point where they do feel it again."
