Poor defending cost liverpool

Jürgen Klopp concedes that his Liverpool side didn't deserve to win in the press conference after the match Klopp said “They deserved it, to be honest. I don’t like to say it but it’s the truth. West Brom deserved it so compliments to Alan and his side.”
Liverpool were ahead withing five minutes through Roberto Firmino but the visitors hit straight back through Jay Rodriguez who put them in front on 11minutes with his second.
A Joel Matip OG put the visitors 3-1 ahead just before the break - after Firminohad missed a VAR-awarded penalty - and while Mo Salah's 25th of the season gave Liverpool hope with 15minutes left, it was not tobe.
Liverpool were out of the FA Cup at the fourth round stage for the third year in a row under Klopp
