A long-term absence for Gomez would be a major blow to Liverpool, who are expected to be without fellow centre-back Virgil van Dijk for the rest of the season after he suffered a severe knee injury against Everton last month. Jurgen Klopp has also been without central midfielder Fabinho, who deputised at centre-back following Van Dijk's injury, but the Brazilian is expected to return to action after the international break.
