Luis Diaz is in Liverpool's squad for today's FA Cup fourth round tie against Cardiff City.
The Daily Mail says Klopp has included Diaz in his squad for Liverpool's FA Cup clash with Cardiff just 48 hours after the Colombian arrived in Merseyside following his January transfer.
Diaz, who Liverpool signed from Porto on deadline day for an initial £37.5million, only arrived on Merseyside at 10am on Friday after waiting for work permit forms in Paris. He started the week in Argentina, where he played in Colombia's 1-0 defeat.
It has been a hectic time for the 25-year-old, who only met Klopp in person for the first time on Friday. Now he is in the squad for the fourth-round tie with the Bluebirds.
"It's not easy to sit around in Paris waiting for the papers," said Klopp. "It is not the best time in your life and doesn't help with recovery. Let's have a look.
"I wouldn't say no because I would be excited as well about giving him a few minutes at a sold-out Anfield."
