Liverpool are enduring a bit of a defensive crisis at the moment. Ragnar Klavan and Joe Gomez are injured and Joel Matip has been ruled out for the rest of the season.
Speaking at his press conference today Klopp confirmed that the club would be without four players that could play as centre back:
"Joel (Matip) is out for the rest of the season, no doubt about that. It's very serious," said Klopp on Tuesday.
"Emre (Can) will at least be very close for tomorrow - but it doesn't look too good. Joe Gomez is not in for two or three weeks.
"Ragnar Klavan is unavailable. If there is a centre-half in the room I am open for talks.
In the absence of more senior figures in defence, Liverpool Echo's James Pearce is reporting that the club could turn to Irish youngster Conor Masterson.
Masterson was one of five Academy youngsters promoted to train at Melwood on Tuesday and the Republic of Ireland underage international has previously captained the club's under-18s and was an unused sub for Liverpool in their FA Cup tie at Exeter in January 2016.
It would be the 19-year-old Dubliner's first taste of the Champions League should he be called into action and although it would be a massive leap for the defender, it would be great to see an Irish player playing at such a high level.
