Birmingham City have signed England Under-21 captain Jake Clarke-Salter from Chelsea on a season-long loan.
The 21-year-old central defender, who spent last season on loan at Dutch side Vitesse Arnhem, has made two substitute appearances for Chelsea.
Meanwhile, 30-year-old striker Lukas Jutkiewicz has signed a new contract with the Championship club until 2022.
Former Burnley and Coventry front man Jutkiewicz, who joined Birmingham in 2016, scored 14 goals last term.
Clarke-Salter previously played in the Championship while on loan at Sunderland from January to May 2018.
He was part of the England side that won the 2017 Under-20 World Cup and has three FA Youth Cup winners' medals.
Under the loan agreement, Clarke-Salter will be eligible to play for Birmingham in the FA Cup and EFL Cup as well as the league.
