Liverpool legend Steven Gerrard
And Gerrard believes Jurgen Klopp’s side now have a lot of work to do in the title race.
“It's going to be very difficult now,” Gerrard told BT Sport.
“They've left themselves a lot of work to do.
“A 10-point gap, if Chelsea win tomorrow, it's very difficult.
“When I played, when we got close the damaging results were against lower teams.
“That dressing room there will be stunned, you can tell by Jurgen Klopp's face.
“Before the game you could see they saw this as a three-point game.”
