"You can look at last season, we lost to Spurs 6-1," he told Sky Sports. "This is worse, miles worse."

He added: "It is not easy to say something apart from it is the darkest day I have had leading these players. We were not good enough individually and as a team, can't give a team like Liverpool those chances but unfortunately we did.

Meanwhile, Real Madrid defeated Barcelona in a new-look El Clasico to take control of La Liga and drop Ronald Koeman's side to eighth place.
