Liverpool midfielder Fabinho has been impressed by Luis Diaz's start at the club.
The Colombian attacker has fitted in seamlessly since his January move from Porto.
Fabinho has struck up a friendship with Diaz and believes he will continue to grow at Anfield.
"He's really impressive," Fabinho told the club's website. "He has been here one month, a month-and-a-half and is playing on a really high level.
"He was really important in the final as well; for me, he was one of the best players in the final against Chelsea.
"I think the final was only his third game maybe with us, so he's really impressive. He is really good. It's not always easy to play at a high level when you change country and change league, he was not used to the intensity of England but he looks like he was playing here a long time because he is playing really well and has been really impressive."
