Thiago Alcantara's injury nightmare has been prolonged with the Liverpool midfielder suffering a fresh setback only five minutes into his latest comeback.
The 32-year-old suffered a muscular problem in Sunday's defeat at Arsenal and could be out for several weeks.
His cameo at the Emirates as an 85th-minute substitute was his first appearance of the season because of a hip injury.
It is the latest blow for the Spanish international whose career at Anfield has been blighted by various medical issues since his £20million move from Bayern Munich in 2020.
