At the home of Manchester City, Liverpool produced a performance worthy of champions to move 11 points clear at the top of the Premier League. A 2-0 win at the Etihad on Sunday extended Liverpool’s lead over second-placed Arsenal and consigned four-time defending champion City to another humbling defeat in an ever-worsening season. On Wednesday a 3-1 loss to Real Madrid sent Pep Guardiola’s team crashing out of the Champions League. Back to domestic matters on Sunday and City was powerless to slow down Liverpool’s march toward the title. Newcastle scored four goals in 11 minutes against Nottingham Forest, but still had to withstand a late fightback to seal a 4-3 win.
