Liverpool midfielder Thiago Alcantara has suffered another injury setback this season.
The pass master was only just back from a long term hip problem, coming on during their 3-1 loss to Arsenal at the weekend.
However, Thiago now appears set for another spell on the sidelines, which is a blow to the club's title charge.
Per The Mirror, the club are hoping that his new issue is only minor and can be resolved.
However, a muscle injury so soon after returning could mean that Thiago has to take a step back and regain full fitness.
He may have rushed back without being in the condition required to stand up to the rigor of Premier League matches.
