Liverpool have completed the signing of defender Ben Davies from Preston North End on a long-term deal.
Jurgen Klopp has been forced to enter the transfer market this winter after injuries to Virgil van Dijk and Joe Gomez left him short at centre-back.
The Reds paid just 500,000 euros to bring 25-year-old Davies to Anfield, with his contract at Preston up at the end of the season.
"What I like about Ben is it just shows that each situation creates opportunities," Klopp said about the transfer on Liverpool's website.
"I think it's probably clear that in a normal transfer window, without any issues, we would not look at Preston if there's a player for us or something like that. It's not really likely.
"But since we saw him and since our situation got clearer and clearer - the problems we had - when we saw him we got really excited about it and thought, 'Wow.'
"He's a boy who played his whole life for Preston, is around the corner pretty much. We see the potential really. We see the quality and we see the potential as well because he's 25 and there's a lot to come for him.
"I love a lot about his play. He's a really good footballer, looks like a proper leader in this Preston team, good in challenges, looks football smart, can play different positions because he played in a back three and a back four and all these things.
"That makes him really interesting so I'm really looking forward to working with him. I know for him it's an opportunity and I see it exactly the same for us, that it's a really good thing to do."
