Liverpool cruised into the fifth round of the FA Cup with a 5-2 rout of Championship Norwich City on Sunday, to kick off Juergen Klopp’s long goodbye at Anfield, while crowd trouble marred Wolverhampton Wanderers’ 2-0 victory over West Bromwich Albion.

Twelve-time winners Manchester United gave up a two-goal lead before escaping from Rodney Parade with a 4-2 victory over fourth-tier Welsh side Newport County.

Liverpool’s beloved manager announced on Friday that he would leave the Merseyside team at the end of this season, his ninth at the helm.

“I get it, it’s very emotional,” Klopp told BBC.

“First match after the news and we can get used to it,” he added.

The eight-time FA Cup winners had goals from Curtis Jones, Darwin Nunez, Diogo Jota, Virgil van Dijk and Ryan Gravenberch.

Liverpool will next play either Watford or Southampton after that fourth-round game earlier on Sunday ended in a 1-1 draw thanks to a last-gasp goal by Southampton’s Stuart Armstrong to force a replay.

Antony scored in the 68th-minute for last year’s FA Cup runners-up after Newport had clawed their way back from two goals down.

Bruno Fernandes, 18-year-old Kobbie Mainoo and Rasmus Hojlund also scored for United, who conceded two goals in an FA Cup match against a fourth-tier side for the first time since 1970 (against Northampton Town).
