Newcastle United winger Jacob Murphy admits he's amazed by the ability of Kieran Trippier.

Murphy has declared the fullback as world class after victory over Crystal Palace on Saturday.

Indeed, he rates Trippier among the best right-backs in the world.

"He's an unbelievable right-back, probably one of the best in the world," Murphy said.

"It was a great start. The key word for us was 'tempo'; we started quick and that got us up and running. It put us in good stead for the rest of the game."
