Goal hero Frank Lampard admits Chelsea can only blame themselves for slipping out of the Barclays Premier League title race after claiming they have "dropped their standards" in recent weeks.
The veteran midfielder also warned it is vital the Blues retain the team spirit built during a decade of success if they are to stay a major force and challenge again for honours.
Lampard said: "If you don't play well enough then you don't get results. It's difficult now. You saw Blackburn against (Manchester) United, Sunderland against (Manchester) City. Teams aren't mugs. They're all set up very well and, if you're not at your very best, you won't win games."
