It means full debuts for the club for Klavan, Wijnaldum and Mane.
Among the subs are new signings Marko Grujic, Joel Matip and former Arsenal keeper Alex Manninger. Divock Origi provides the forward option from the bench. Can and Kevin Stewart are the other two bench options.
Can and Origi aren’t considered fully fit having returned to pre-season later due to their Euro 2016 commitments. Klopp opts for players with the most fitness from pre-season to begin the season, as he hinted at in his pre-match press conference on Friday.
For Arsenal, mew midfield signing Granit Xhaka is named on the bench. Alexis Sanchez starts up front.
