Sheffield Wednesday have signed Tottenham midfielder Josh Onomah and Chelsea centre-back Michael Hector on season-long loan deals.
England Under-21 international Onomah, 21, played 33 league games while on loan at Aston Villa last season.
Ex-Reading defender Hector, 26, has not played a first-team game for Chelsea since joining for £4m in 2015.
He spent 2017-18 on loan at Hull, making 38 appearances, and also had a spell with Eintracht Frankfurt.
Onomah has featured in 32 games for Tottenham, but has yet to make a Premier League start.
