Development goalkeeper Ollie Webber has joined Portsmouth on a permanent basis, after six years in south London. The Northern-Irishman arrived at Palace from Glentoran in 2016, and won the league with the Under-18s in 2017/18.
Last season he was a crucial part of the Under-23s' promotion-winning campaign, keeping a clean-sheet in the play-off final as the young Eagles won on penalties.
Everyone at the club wishes Ollie all the best with the next step in his career.
