Chelsea and England Under-21 midfielder Conor Gallagher has joined Crystal Palace on a season-long loan.
Gallagher, 21, has a Blues contract until 2025 but is yet to make a first-team appearance and has spent the past two seasons on loan gaining experience.
Last term, he made 32 appearances as West Brom were relegated from the Premier League.
"I'm buzzing to be here. I can't wait to get started, I'm happy to get the deal over the line," said Gallagher.
"I spoke to the manager, I liked what he said, I liked how he wants to play, how he wants me to play and how he wants the team to play.
