Jurgen Klopp says he's never seen a player react to training exercise like Luis Diaz

Jurgen Klopp is delighted with Luis Diaz's attitude since arriving at Liverpool as he insists there is "a lot more to come" from the Colombian.

The forward has not taken long to settle into life on Merseyside following his £50million switch from Porto last month.

Diaz impressed on his debut against Cardiff as he climbed off the bench to help the Reds secure a 3-1 win in the FA Cup fourth round at the weekend.

The attacker provides Liverpool with another devastating option up top and can play anywhere along the frontline.

And Klopp is over the moon with the way he has made an immediate impact on and off the pitch.

The German praised his positivity in training this week and says he has never seen a player so upbeat during a rondo, a training exercise where a group of players are tasked with keeping possession off an individual.

"I liked his contribution when he came on in the Cardiff," Klopp said of Diaz. "Yesterday, he enjoyed his training session a lot.

"I'm not sure I ever saw a player smiling so constantly during a rondo. We can see he fitted in during the last game, he played exactly as we wanted him to. There's a lot more to come."

Diaz is in line for his Premier League debut against Leicester and has spoken highly of his time at Liverpool so far, as well as his teammates, according to his father Luis Manuel Diaz.

"After the first game, he told me that it was a team that works hard, complete, in which he will feel comfortable and will have the chance to play with high-performance players," Luis Manuel told Colombian radio station Bluradio, via the Liverpool Echo.

And Diaz's compliment has been returned by a member of the squad, Harvey Elliott, who came on as a substitute at the same time and scored a goal
