At the halfway stage of the Premier League season, Liverpool have stolen a march on title favourites Manchester City to lead by six points.
But perhaps the standout number in the league table is the zero in Liverpool’s loss column. That means they are halfway to emulating the Invincibles team of 2003/04, who completed an unbeaten season under Arsene Wenger.
Can Liverpool match that astonishing achievement? As Manchester City found out last year it’s a very tall order, but our head coach thinks it could happen in 2019.
"They can do that because they are doing it at the moment," said Unai Emery.
"We played against Liverpool three years ago with Sevilla in the final of the Europa League and I look then, at this progress, in this process and they are a very good example.
"I am also looking, with the coaches also, at how we are now and with the difference in the table before those years and with us and with other teams.
"The progression with Liverpool is clear. Three years ago, they were out of the Champions League through the Premier League and through the Europa League, because they lost against us [at Sevilla].
"This progress is also one example for us, now, in our moment. But we need to be very, very demanding of ourselves to do this step quickly in our way. But we need also time, and sometimes the patience is very important for us."
