Liverpool's latest injury casualty could see Jurgen Klopp get creative with his defence as his options at the back begin to run out.
Joe Gomez reportedly picked up a serious-looking injury during England training on Wednesday, and he could well join Virgil van Dijk on the sidelines for the foreseeable future.
With the injury-prone Joel Matip and Fabinho the only other two senior centre-backs available to Klopp, the German has been left with a big decision to make.
Either he puts his faith in youth, with the likes of 19-year-old Rhys Williams and 18-year-old Sepp van den Berg possible options.
Or he could revert to a previously-mentioned backup plan - with former Reds man Javier Mascherano proving an inspiration.
Mascherano played for Liverpool for four seasons before moving to Barcelona, and despite spending the majority of his career as a defensive midfielder he ended up becoming a centre-back further down the line.
And as recently as last month Klopp mentioned a number of his players who could potentially make a similar move to that of Mascherano.
Speaking ahead of his side's match against West Ham, when asked about his troubles in the centre-back position Klopp said: "We have other options like [Jordan] Henderson, or Gini [Wijnaldum] or James [Milner], or Robbo (Andy Robertson), he can play centre-half as well.
"They are all not smaller than Javier Mascherano, for example, and he played pretty well in that position [for Barcelona]."
Considering Liverpool have a far greater strength in depth in both the central midfield and full-back positions than they do in central defence, perhaps the idea does not seem too far-fetched.
If either Henderson or Wijnaldum filled in at the back, for example, the likes of Thiago Alcantara, Naby Keita, Alex Oxlade-Chamberlain or Curtis Jones could slot in in midfield, while Robertson or Milner could be covered by the likes of Kostas Tsimikas at full-back.
Judging by Klopp's comments, this is certainly a scenario the German boss has thought about before, and it will be intriguing to see what line-up he goes for after the international break when the Reds take on league leaders Leicester City.
Supporters may just be in for a surprise or two.
