Liam Rosenior has yet to pick an unchanged back four for a Chelsea league fixture.
Backers of such an approach would point to the fact the six games he has taken charge of in the Premier League do not contain a single defeat for the Blues.
But pundits Wayne Rooney and Micah Richards discussed the lack of continuity on Match of the Day on Saturday in the aftermath of Chelsea's 1-1 draw with Burnley.
Asked if a consistent back four is a good starting point for a manager, Rooney said: "Yes. Absolutely. It's happened all season. It was happening with the previous manager.
"Chelsea have that many players, to juggle players around, you don't know if there's pressure from above to do that. You just don't know who the leader is in there? The defenders are similar in how they play and I don't see a standout leader."
Richards offered: "He's still trying to find his best back four."
So, is this a concern? Or are there other issues creating problems for Rosenior?
