Tottenham 1-2 Newcastle: Postecoglou's Spurs in freefall
Ange Postecoglou's team could hardly have wished for a better start against in-form Newcastle, but Dominic Solanke's early goal was as good as it got against the Magpies.
Spurs were behind seven minutes before half-time and despite an improved second-half display, they failed to trouble goalkeeper Martin Dubravka enough to salvage something from the game.
Spurs were adamant Joelinton should have been penalised for handball in the build-up to Anthony Gordon's equaliser, but the officials deemed that the contact with Lucas Bergvall's pass was accidental and that the Brazilian's arm was in a natural position.
Their latest defeat means Spurs have picked up only five points from their last eight in the league, while their run of six home league matches without a win is their longest since an eight-game streak under Juande Ramos in 2008.
They have not kept a clean sheet in the Premier League since a 4-0 victory over Everton back in August - 10 matches ago.
Debutant goalkeeper Brandon Austin could do little about Newcastle's two goals, while the introductions of Son Heung-min, James Maddison and Yves Bissouma with half an hour to play failed to turn the tide on another deeply frustrating afternoon for Postecoglou and his players.
