Chelsea are looking to sign a right-back because Roberto Di Matteo has no depth in that position.
Should Branislav Ivanović succumb to injury (again), it remains to be seen if Paulo Ferreira is good enough to start an extended batch of games.
If both Ivanović and Ferreira are out, who plays at right-back? Ramires?
Injury aside, Ivanović's discipline has been wayward of late.
He infamously missed last season's UEFA Champions League final after being booked in the semi-final second leg for scuffing the penalty spot.
At the time, what seemed an innocuous act had far-reaching ramifications because Lionel Messi inexplicably failed to score from 12 yards out.
If Ivanović knew one more yellow card meant being suspended for the final, he probably wouldn't have attempted such a desperate act. In hindsight, it was an act which helped Chelsea overcome Barcelona.
Then, there was the Serbian's three-game suspension for striking Shaun Maloney.
In the Community Shield loss to Manchester City, Ivanović was sent off for a tackle on Aleksandar Kolarov that looked worse on replay.
Chelsea are fortunate that the FA doesn't categorise the Community Shield as a "competitive first team fixture".
