While most people are taking aim at Robert Sanchez as they look to apportion blame for yesterday's defeat to Liverpool, Simon Johnson is looking elsewhere.

His piece for the Athletic today focuses on Chelsea's central defenders, a part of the team which of course closely interacts with the goalkeeper, and can affect or be affected by issues in that part of the pitch too.

Johnson notes that Chelsea have spent vast sums on defenders, yet haven't found the dominant pair (or even the dominant individual) which the team can hang its hat on and rely on to be a rock at the back every week. For all the talent we have, there still is a lack of "brick wall" to the back line:

Signing Tosin Adarabioyo on a free transfer and promoting Levi Colwill from the academy has added to the strength in depth," the writer noted.

But mitigating circumstances and talent don't win you games, and yesterday was lost in large part because of poor play at the back. Colwill gave away a penalty, then the whole defensive line froze and Sanchez failed to come on the second half Mo Salah cross which Curtis Jones met to give the home team the lead.

This is a huge test of Enzo Maresca's ability, as the coach must develop defenders as well as attackers if he wants to take Chelsea to the next level.
