#3 Error-prone Chelsea
Frank Lampard's Chelsea begun this season with a reputation for defending poorly, and although they have repaired that image to some extent in their last few games, it still largely holds true.
Against Valencia, their defending was much better, but they developed a dangerous habit of committing errors within their own half. Kepa's error was the most threatening as he ended up playing the ball to the opponents' feet directly at least once. He was also caught in no man's land when Jorginho's wayward pass was intercepted and Rodrigo's shot sailed over the bar.
The Italian midfielder and Willian were both guilty of trying to play a pass too many in risky areas often leading to turnovers in areas that Valencia could capitalise upon. The profligacy of their forwards spared the Blues any blushes. However, Chelsea's midfield, in particular, needs some more defensive solidity.
