The Brazilian, 21, moves to St James's Park having made five appearances for Chelsea this season.

A versatile left-sided player, Kenedy moved to Stamford Bridge in the summer of 2015 from Fluminense and netted the fastest Premier League goal of that campaign when he opened the scoring in an away game at Norwich after just 39 seconds.

This season he has featured in both domestic cup competitions for the Blues, and is ineligible for this weekend’s FA Cup fourth round game at Stamford Bridge.

Newcastle are currently 15th in the Premier League table.
