The 23-year-old, who has been capped twice by Serbia, has agreed a seven-year contract at Stamford Bridge, with a club option of a further year.

On completing his transfer, Petrovic said: ‘I’m so happy to be at Chelsea and I’m really excited to get started at this club.

‘It’s a big step for me and it’s always been a dream of mine to sign for one of the biggest clubs in the world. Today I have achieved that goal and I’m so happy.

‘Playing in the Premier League is something I’m really looking forward to doing and I hope to learn many things here at Chelsea. I can’t wait to meet everyone and play at Stamford Bridge.’

Co-sporting directors Paul Winstanley and Laurence Stewart said: ‘We are very pleased to welcome Djordje to the club. His performances in MLS have earned deserved praise and recognition – and have prepared him for the challenge of playing for Chelsea.

‘Djordje improves an already strong goalkeeping team. We look forward to watching him work under Mauricio Pochettino, goalkeeper coach Toni Jimenez, and the rest of the first-team staff this season.’

Petrovic started his career in his native Serbia and represented both Rudar Kostolac and Presing Pozarevac before joining Cukaricki in 2014. 

After progressing through the club’s youth rank ­– and spending time on loan at FK IMT – his first-team debut for Cukaricki came against Mladost in 2019. From that point on, Petrovic established himself as first choice. 

He went on to make 86 appearances for Cukaricki before completing his transfer to New England Revolution in April 2022. 

Petrovic quickly became a key figure in the Revs side. He made 21 appearances during the 2022 campaign and was nominated for the MLS Newcomer of the Year Award and the MLS Goalkeeper of the Year Award.

A further 22 appearances were made this season, and Petrovic also featured for the MLS All-Stars against Arsenal this summer.

Welcome to Chelsea, Djordje!
