Virgil van Dijk has made a dream start to his Anfield career, scoring the winning goal on his debut for Liverpool, as they beat rivals Everton 2-1 in their FA Cup third round tie.
The Dutchman, signed last week from Southampton for a reported fee of STG75 million pounds (NZ$141 million), rose inside the area to head home an Alex Oxlade-Chamberlain corner in the 84th minute of what had been a pulsating Merseyside derby.
Gylfi Sigurdsson brought Everton level in the 67th minute after a brilliant counter-attack from Sam Allardyce's side.
The home side had taken the lead through a 35th minute penalty from James Milner after Everton defender Mason Holgate pulled down Adam Lallana in the box.
In the day's other match, Jesse Lingard scored his fourth goal in as many games and substitute Romelu Lukaku added a stoppage time effort as Manchester United reached the fourth round with a 2-0 home win over Championship side Derby County.
Lingard, who has scored three goals in his last two matches, produced another exquisite finish as he unleashed a shot from 18 metres in the 83rd minute.
Derby looked set to earn a reply after United had missed a string of chances, with Marcus Rashford also hitting the woodwork, while visiting keeper Scott Carson produced a barrage of good saves.
Lukaku, who returned from a head injury and came on as a halftime substitute for Henrikh Mkhitaryan, broke away and powered his shot past Carson at the death.
