Liverpool fullback Andy Robertson has heaped praise on Luis Diaz following Sunday's derby win over Everton.

The Colombian, signed from Porto in January, was a constant threat going forward for Liverpool as they ran out 2-0 winners over their fierce rivals.

Diaz pulled out an outrageous piece of skill in the second-half when he brought down Trent Alexander-Arnold's cross-field pass with a deft backheel.

Robertson scored the opening goal of the match, and the Scotsman reserved praise for his teammate after the match.

"Diaz has been unbelievable since he has come in," said Robertson.

"The impact he has had on the squad.

"The way he plays is different and he has been exceptional."
