England midfielder Ross Barkley completed a move to Chelsea from Everton on Friday with the London club saying the 24-year-old had signed a 5-1/2 year contract.

Barkley, who has not played for Everton this season because of a hamstring injury having turned down a move to Chelsea in the close season.

Barkley made 150 Premier League appearances for the Merseyside club he joined as an 11-year-old, making his league debut in 2011.

The move to the English champions offers a new challenge for a player who has struggled to live up to the high expectations that greeted his arrival in the Everton first team.
