The Scottish Premiership side currently have two of their centre-back options out injured.
The Hoops won the Scottish Premiership title last season, but largely failed in their other competitions. One of the reasons for their struggles was the difficultly that Ronny Deila had in being able to stick with a regular defensive partnership.
The likes of Erik Sviatchenko, Charlie Mulgrew, Dedryck Boyata and Jozo Simunovic all enjoyed spells in the team, but Rodgers' predecessor's hand was often forced as to which two he selected due to injuries.
And ahead of the start of their Champions League qualification campaign, there are question marks surrounding the latter two of the quartet's chances of being fit for the upcoming games, with the Evening Times reporting that Simunovic is a major doubt for the fixtures.
And with the Hoops potentially being without another of their options for their European bow - the Evening Times reports that Mulgrew is out of contract and has only been offered reduced terms - Rodgers has outlined the importance of his centre-backs becoming much more resilient.
"It's an area where you need to be robust," he told the Evening Times. "If players are going to play 50 or 60 games a season you normally find that your centre-halves will play those games.
"So at the minute we have a few of those injured and not fit. But it's where it’s at and we need to look to see when we can get them back. If they are not going to be ready it's a scenario we need to look at."
Though their current lack of options is less than ideal, the problems that Deila endured during his last year with the club would have surely not gone unnoticed when Rodgers was assessing his squad following his arrival. Thus, he may have already felt that adding depth in that area of the pitch was necessary anyway.
