The 20-year-old arrives at Stamford Bridge having earned valuable experience in both the Bundesliga and UEFA Champions League, recording well over 100 appearances for the German side since making his debut. He has also been capped at Under-21 level for England.

‘It feels great,’ Gittens said. ‘It’s a great feeling to join such a big club as Chelsea.

‘I can’t wait to learn from everyone in the team and to push myself to the max here. It’s an amazing feeling.’

Gittens made the move to Germany from Manchester City in 2020 and quickly established himself as part of the first-team squad at Signal Iduna Park. He made his debut late in the 2021/22 season before having a breakout campaign the following term, netting his first senior goal in August of that year.

Gittens featured heavily across the Bundesliga, the Champions League and the DFB-Pokal, making 20 appearances and scoring three goals. The following season, he registered 10 goal contributions in 34 appearances across all competitions.

Gittens continued to impress for Dortmund during the 2024/25 campaign with 17 goal contributions across all competitions, before featuring for the German side in the FIFA Club World Cup.

Comfortable playing on either flank, Gittens adds further top-flight experience to the Chelsea squad.

Welcome to Chelsea, Jamie!
