Albion have confirmed the signing of Billy Gilmour from Chelsea.

He has agreed a four-year deal and arrives for an undisclosed fee thought to be about £7.5million initially.

The 21-year-old Scotland midfielder is available to play against Leicester on Sunday.

Albion boss Graham Potter said: “Billy arrives with a fantastic pedigree, having played in the Premier League and Champions League as well as for Scotland at last year’s Euros. He will complement our existing midfield options.

“That experience at quite a young age shows the strength of character he has and we’re really excited by his potential.

“Now it’s about allowing him the time to get used to a new environment and settling in to our club. We can’t wait to work with him.”
