Jurgen Klopp is sweating on the fitness of Alisson Becker and Thiago Alcantara as he looks to maintain Liverpool's winning start to the season.
Goalkeeper Alisson and Thiago, the £20million signing from Bayern Munich, missed weekend training and the absence of both men — who were crucial to last week's win at Chelsea — would be a significant blow.
Adrian, Liverpool's Spanish understudy, is waiting to take over from Alisson but who replaces Thiago in midfield is an issue Klopp must solve. He is already without Jordan Henderson and Alex Oxlade-Chamberlain, while Fabinho may be needed to partner Virgil van Dijk in central defence.
