Marco Streller helped FC Basel beat Liverpool 1-0 in a UEFA Champions League match on Wednesday to allow the club to claim second spot in Group B.
According to the BBC, Liverpool's hopes of making it to the Champions League knockout stages have been dented by this loss.
With back-to-back meetings against holders Real Madrid to follow in Group B, Liverpool will need a vast improvement to progress to the knockout stages.
Streller has scored five goals in eight games in the Swiss top flight this season
Basel beat Chelsea home and away in last season's Champions League group stages.
