London clubs Chelsea and Tottenham Hotspurs both secured easy victories against Peterborough United and Aston Villa respectively to progress to the fourth round of the FA Cup.
The Blues had captain John Terry sent off, but a dominating display saw Pedro score a brace and Michy Batshuayi and Willian also got on the scoresheet to earn Chelsea a 4-1 victory over Peterborough United on Sunday.
Tottenham Hotspur joined fellow London clubs Arsenal and Chelsea in round four by beating Aston Villa 2-0 at White Hart Lane.
Liverpool, on the other hand, faces a replay at fourth-tier Plymouth Argyle after Klopp’s decision to use a second-tier team backfired and the team was held to a 0-0 draw at Anfield.
Jurgen Klopp made 10 changes for the visit of Plymouth, his side’s average age of 21 years and 296 days making them the youngest team in the club’s history.
“I don’t know how many people live in Plymouth, but it felt like the whole of Plymouth was in the 18-yard box,” Klopp told BT Sport.
“It is not a result we wished for, but it is not frustrating — that’s football. Plymouth deserved the draw and the rematch.”
Plymouth manager Derek Adams said: “We are delighted to take them back to Plymouth.”
Grant Leadbitter, Alvaro Negredo and Marten de Roon all got on the scoresheet while Daniel Ayala was sent off as Middlesbrough avoided an upset by beating Sheffield Wednesday 3-0 at the Riverside Stadium.
Ryan Sessegnon became the youngest goal-scorer in the full FA Cup – minus preliminary rounds- after scoring at aged 16 years and 235 days in Fulham’s 2-1 win at Cardiff City.
