Liverpool won two cups - the FA Cup and the EFL Cup - last season, narrowly missed out on the Premier League title and lost in the Champions League final.
This year has been much tougher and they are sixth in the Premier League and have to face Real Madrid in the last 16 of the Champions League.
Liverpool defender Andy Robertson, speaking to BBC Radio 5 Live: "There were positives, creating chances, sometimes we looked good on the ball but there were mistakes as well. It's our first game back in a long time and it's not often you're first game back is against Manchester City.
