Palmer’s new contract at Chelsea commits him to the club until 2021, and he will now experience his first season as a Premier League player.

The 20-year-old attacking midfielder, who joined our Academy as an Under-16, played a significant part in the Yorkshire club’s promotion from the Championship last season.

He made 27 appearances and scored five goals and although injury ruled him out for a period in the second half of the campaign, he returned in time to come on as a substitute in their play-off final win over Reading.
